Geologic setting

Geologic description

This occurrence consists of galena and malachite in maroon and white, muscovite quartzite (Dillon and others, 1981 [AOF 133B]). An analysis of a composite rock sample, however, showed no anomalous metal values. The rocks in the area consists of Devonian, Hunt Fork Shale near its thrust contact with overlying Devonian, Skajit Limestone (Dillon and others, 1986). A small area of Devonian(?) siliceous, clastic rocks is nearby. No other information is available.
