Preliminary report on geophysical survey of the Janina lease, Barrona county, New South Wales

Abstract

Gravimetric and magnetic investigations have been carried out by the Bureau during October and November 1950 in order to find favourable locations for artesian water bores on lease No. 5893, known as Janina and situated in Barrona County. The geophysical survey was requested because two bores recently drilled on the lease failed to produce artesian water, although artesian water bores previously completed in the area adjacent to Janina lease proved the existence of certain aquifers yielding sufficient quantities of good water. Results of the geophysical fieldwork as correlated with data obtained from boring indicated a gentle uplift of basement rocks and water bearing strata, trending from NE to SW and occupying more or less all of the center part of Janina lease. No indications could be derived however from geophysical data as to a relatively steep uplift of basement rocks in the vicinity of bore No. 8153. Hard strata of sandrock and quartzite encountered by this bore at approximately 470 to 480 feet therefore must be classified as probably being of local character. Further drilling operations for suitable water supply naturally should avoid the aforementioned structural high, which is apparent from both boring data and gravitational work.
