... measured from 80 holes drilled on a kilometre-spaced grid. A numerical model was developed to quantify the groundwater flow regime in the study area. Also, hydrogeological data in combination with the geochemistry of the waters were used to identify a complex flow regime adjacent to Lake Lefroy, a playa...

... Lake Lefroy in Kambalda, Western Australia. The main objective was to map exceptionally complex, deep structures associated with Kambalda dome. Survey design used 3D ray tracing to improve the distribution of the common reflection points across ultramafic-basalt contacts which host numerous small, high...

The camp itself is 40 km long and 10 km wide trending south–southeast from Kambalda on the southern tip of the Norsemen-Wiluna greenstone belt of the Yilgarn craton. The color of Lake Lefroy on Figure  1 slightly is misleading, because the lake...
