This existing listing which at the time of checking (since updated) was without a reference is not referring to a mine or mineral specimen locality, but relates to a university study of a small area of the Reynolds Range.
The Reynolds Range is a range of hills 130 kilometres long, trending north-west to south-east, about 150 kilometres north-west of Alice Springs.
It preserves a coherent stratigraphy from greenschist to granulite-facies grades, and has a prior history of contact metamorphism, making it an ideal place to examine the complicated history of fluid-rock interaction. As such it tends to get geology professors excited and has been much studied. A lot of the information involves detailed technical discussions about how the regional scale rocks were formed, and is beyond the scope of Mindat.
The study area for kornerupine was approximately 5 kilometres south of Pine Hill within the southern area of the ranges. No information could be found as to whether crystal specimens were observed like at Harts Range, as the study was more focussed on how the kornerupine provides evidence towards the formation of the rocks in the area.
The main interest is some of the kornerupine is nearly boron-free (0.45 wt.% B2O3), being at the time, only the third discovery of boron-free kornerupine worldwide. It is locally abundant in pods and lenses, is coarse grained, non-foliated, Mg- and Al-rich, occurring in high metamorphic grades in early Proterozoic metapelitic rocks.
The low- and high-boron kornerupine pods are separated by as little as 10 metres, indicating the composition and amounts of metasomatic fluids which formed them varied on a local scale. The pods are surrounded by foliated cordierite-quartzite rocks.
The Range runs through Jervios Station.
