GSC/TSD-2000-Ranch Lake 76E South Till: I and M Morrison IM grain counts

Type: lab data

Bundle Description

Heavy mineral concentrates from Ranch Lake (NTS 76E South) till samples processed by Canamera and Diamond Indicator Processing were picked by I and M Morrison of Delta, BC for 6 kimberlite indicator minerals (KIM-including pyrope garnet, eclogitic garnet, chrome diopside, magnesian ilmenite and chromite). Only a portion of the non-magnetic 0.25-0.5 mm fraction of the Ranch Lake samples (indicated by a _N after the sample number in the appendix) was examined due to the abundance of indicator minerals. The raw values from those samples were normalized to the 0.25-5 mm non-magnetic weight fraction to give an estimate of the number of indicator minerals in the sample.The 0.25-0.5 mm and 0.5-0.84 mm fractions of till were picked.

These data are published in GSC Open File 3924
