Sun moths (Castniidae) constitute a small family of day-flying butterfly-like moths that have their centers of diversity in South America and Australia. Here we describe a new castniid from the Finders Ranges, South Australia. Synemon arkaroola spec. nov. is similar and related to Synemon brontias Meyrick, 1891 but differs by a number of external and genitalic characters, including the extensive bright orange markings on the hindwings. The new species inhabits dry creek beds and adjacent slopes where the hostplant, Scented Lemon Grass, Cymbopogon ambiguus (Hack.) A. Camus (Poaceae), grows.

AbstractA low-cost differential image motion monitor (DIMM), consisting of an 11-inch Celestron, an SBIG ST-4 autoguiding CCD camera and a PC, is described. Two such systems were used during June–July and November–December 1993 to make near-simultaneous seeing measurements at Freeling Heights in the Northern Flinders Ranges and at Siding Spring Observatory. The results of these campaigns show that the seeing-distribution is generally similar at both sites, with the most common seeing value being ~l·2″. Siding Spring does, however, have slightly more bad seeing (>2″) than Freeling Heights. Weather records from Arkaroola Resort (15 km south of Freeling Heights) indicate that there is ~15% less cloud cover at Freeling Heights than at Siding Spring. Episodes of rapid seeing deterioration at Siding Spring in winter are shown to coincide with warm air masses crossing the mountain.

Arkaroo Rock, an important Aboriginal art site located in the Flinders Ranges National Park, South Australia, features a range of artworks created using red and yellow ochre along with white minerals (such as kaolinite, and gypsum) and charcoal. The site is widely promoted to tourists and, during peak season, attracts more than fifty visitors each day. In mid 2007, the local indigenous community noted that the art was covered with a dust-like substance, the nature of which was unknown. It was hypothesised that the substance was the result of local soil adhering to the surface of the artwork with the morning dew. In order to preserve the site, cleaning and conservation work began in early 2008. This study presents an investigation into the source of the particulate matter covering the artworks. Prior to the conservation work commencing, samples were collected from various locations on the rock, within the protective fence surrounding the artwork, and the surrounding soil. Plant samples were also collected proximal to the artwork. A number of techniques were used to characterise and identify the origin of the particulate material from the rock surface. These techniques included optical microscopy, X-ray diffraction (XRD), thermal gravimetric analysis (TGA), colour analysis based on the ES-1000 EFI spectrophotometer (UV-Vis), and subsequent multivariate statistical analysis. Results of this study are presented here, including detailed results obtained from an emerging colour-based ES-1000 EFI spectrophotometer method along with TGA, optical microscopy and XRD. Results confirm the presence of morning dew in surface samples, and eliminate local sources as the origin of the particulate matter.

The Neoproterozoic to Cambro-Ordovician sediments of the Adelaide Rift Complex (formerly Adelaide Geosyncline) have been the focus of extensive investigation. Despite this, comparatively little is known about the Earliest Adelaidean Callanna Group sediments, due to their sparse preservation in outcrop geology. Exposure of the Callanna Group, and structures related to early Cryogenian graben formation at Arkaroola, in the northern Flinders Ranges, provides a unique opportunity to unravel the local geometries of rift initiation. These rocks have been subjected to multiple intracontinental deformations, most notably the Delamerian Orogeny. Through detailed structural mapping and analysis it is possible to propose models of tectonic evolution for this area. Previous regional scale mapping of the northern Flinders Ranges has identified a disparity between the tectonic history of the Arkaroola Basin and broader northern Flinders Ranges. The nature of the rifting and orogenic evolution of the Arkaroola Basin is determined though analysis of field data, rock samples in thin section and EBSD analysis. Graben formation accommodated an initial period of clastic and evaporitic deposition, followed by rift related basalt extrusion. This was followed by several phases of localised rifting and deposition, controlled by evolving fault geometries. Broad-scale orthogonal folding has folded an earlier composite fabric in conjunction with bedding. This initially planar fabric, most notable in the Woodnamoka Phyllite, formed during peak metamorphism of at least 500° C and approximately 3 kbars and is primarily attributed to burial beneath a thick pile of rift and sag phase sediments, coupled with a change in horizontal stresses. This is loosely constrained to post-rift cessation and before a previously indentified thermal pulse, ca 440 Ma. A set of NE-SW trending faults in the basin have been identified as En echelon stepovers of the Paralana Fault system, responsible for the formation of the pull-apart geometries. This system of faults details a strike-slip duplex, the reactivation of which, coupled with an anomalously high-heat producing basement, has controlled and localised deformation of the Arkaroola Basin.

The lowermost Adelaidean sequences exposed to the immediate north of Arkaroola are unusual as they exhibit a localised complexity of deformation and elevated metamorphic grade that is not observed elsewhere in the Adelaide Fold Belt. Deformation and metamorphism in Arkaroola is thought to have formed as part of the Delamerian Orogen approximately 515-490 Ma. The timing of deformation and metamorphism however is poorly constrained in this area. This paper aims to discuss the structural and metamorphic conditions in the area to determine if there was a possibility of a pre or post-Delamerian structural and/or thermal event. A section was mapped to the North-East of the Arkaroola Homestead to gain an insight into the structural and metamorphic conditions of the area. Samples were collected from the field and used for microstructural analysis. An Electron Microprobe, Laser Ablation Inductively Coupled Plasma Mass Spectrometer and an XRF spectrometer were used for geochemical analysis on the samples. Structural and stratigraphic observations combined with microstructural analysis of samples from the field helped the author create an interpreted geological history of the area. Graben formation accommodated an initial period of sediment deposition followed by basalt extrusion. Several phases of localised rifting and deposition followed this initial deposition period due to changing fault geometries. A mineral fabric that occurs parallel to bedding is seen throughout the study area. This fabric is overgrown and included in prominent cordierite porphyroblasts that formed during peak metamorphism of ≥500 °C at a pressure of approximately ~1.30kbars. These pressure and temperature conditions were primarily due to the burial beneath a thick cover of sediments. A number of faults trending in a NE-SW direction have been identified as splays from the Paralana fault system. The strike-slip movement of the Paralana Fault along with the high heat producing basement of the Mount Painter Inlier has controlled the localised structural complexity and elevated metamorphic grade in the Arkaroola area.

The Paralana Fault Zone is situated on the eastern flank of the northern Flinders Ranges and separates the Mesoproterozoic Mount Painter Domain to the west and the Mesozoic-Cenozoic Lake Frome Embayment to the east. West-over-east neotectonic faults within the fault zone have been identified previously; the main ones having been described in literature but to date there have been no regional structural studies focusing on the geometry and kinematics of the Paralana Fault Zone. The fault zone juxtaposes uraniferous granites of the Mount Painter Inlier and the sandstone-hosted uranium deposits of the Lake Frome Embayment. Due to their proximity to such prospective zones of economic mineralization, understanding the interplay between these faults and the groundwater of the area is of crucial importance for future mineral exploration strategies. We have identified three individual thrust fault sets from a total of 56 catalogued faults, within an area of 150km2. Fault Set 1 strikes approximately NW-SE with moderate dip in both directions and a NE-SW principal stress direction (σ1). Fault Set 2 strikes N-S and has a shallow dip and E-W σ1. Fault Set 3 has an overall NE-SW strike, moderate dip, and is representative of the current stress regime with a σ1of NW-SE. Fault Set 3 features spectacular examples of neotectonic faulting, with Mesoproterozoic marbles and granites of the Mount Painter Inlier overlying Quaternary sandstones and conglomerates of the Frome Embayment. Observed fault displacements since the end of the Miocene range from 10 cm up to an estimated maximum of 800 m. We have sampled fault rocks from 34 measured faults and characterized micro textures ranging from unconsolidated fault gouge and breccia to heavily silicified fault gouge, indicating a range of fluid-flow conditions. To understand the possible fluids to have flowed through the faults, a hydrogeochemical study was conducted with water samples taken from range-proximal natural springs. After careful consideration of the fault orientation and attitudes, fault rock textures and chemical composition of spring waters, I conclude that there is no evidence for direct interaction between surficial neotectonic faults and uranium-bearing fluids.

The lowermost sediments of the Adelaide Supergroup near Arkaroola display pronounced structural complexity and anomalously high metamorphic grade. The timing of the structures, fabrics and metamorphism in the region remain unconstrained, although all are currently interpreted to have occurred during the Delamerian Orogeny. Monazite U/Pb geochronology provides a useful technique for dating amphibolites facies rocks and, combined with map scale and micro structural observations, suggests the peak metamorphism and at least one deformation event occurred significantly earlier than the Delamerian Orogeny. Monazite derived 206Pb/238U age estimates place the timing of peak metamorphism at 705.2±7.4 Ma with observations from thin section revealing a bedding parallel fabric pre-dating peak metamorphism. U/Pb analysis also reveals a second monazite growth event at 644.2±8 Ma the cause of which is hypothesised to be fluid related. Regional folding and axial planar fabric generation post-dates this metamorphism and can be seen to overprint the earlier fabric and wrap the cordierite porphyroblasts. This final deformation event remains largely unconstrained as in situ dating of monazite was not possible in this study. The inferred parasitic relationship between the folds within the studied region and the Arkaroola Syncline which folds the youngest sediments in the Adelaidian Sequence allows for the deposition to be constrained subsequent to the conclusion of the Adelaide Rift Complex.

The rift and deformational evolution of the Adelaide Fold Belt’s northern-most extent, the northern Flinders Ranges, has received comparatively little attention than that of the southern Adelaide Fold Belt. The Arkaroola area, located in the mid-north northern Flinders Ranges, exposes the lowermost Adelaidean stratigraphy of this rift complex, the Callanna and lower Burra Groups, in a near complete sedimentary sequence. The rift history of this stratigraphy is complex, with deposition being largely controlled by the northeast-southwest orientated Paralana Fault and similarly orientated local growth faults. Locally, the Paralana Fault deviates from its regional orientation and forms a north-south striking segment, which under a considered sinistral strike-slip regime during extension would potentially create localised transtension in a ‘releasing bend’ environment. Rifting in the Arkaroola area is therefore considered to be analogous to the formation of a pull-apart basin. U-Pb dating of detrital zircons from the Paralana Quartzite, Humanity Seat Formation and Blue Mine Conglomerate from the Callanna and lower Burra groups yields ages that are comparable to local source regions the Gawler Craton, Mount Painter Basement Complex and the Curnamona Province, and suggest proximal derivation during early rift phases. Sm-Nd bulk rock analysis on the finer grained Woodnamoka Formation implies derivation from the Mount Painter Basement Complex or the upper Willyama Supergroup of the Curnamona Province, the latter of which potentially suggests a more distal provenance region outside of the Australian continent. Deformation in the northern Flinders Ranges has previously been largely ascribed to the ca. 500 Ma Delamerian Orogeny. However, the Arkaroola area exhibits complex deformation not observed in the directly overlying gently folded stratigraphy. Reactivation of pull-apart rift structures during transpression is considered a possible mechanism for producing and localising such deformation. The possibility of an early Neoproterozoic deformational event occurring prior to deposition of the lesser-deformed overlying stratigraphy is also considered, but in lieu of an unequivocal orogenic unconformity, cannot be confidently ascribed. Temporal constraints defined by this study are too broad to accurately define the timing of deformation, and therefore its timing and potential relationship to the Delamerian Orogeny remains largely enigmatic.
