Calcite and Limestone
February 2017 by Chris RalphThe other distinguishing feature of calcite has to do with its chemistry. Geologists sometimes take a small bottle of dilute hydrochloric acid out into the field with them because calcite reacts with acids to make a bubbly foam.
When prospecting for lithium, after confirming for macro attributes through research and field work, including examination of surface geology, the main tool is an accurate lithium assay.
The big interest to prospectors thinking about the effect of erosion is not what might happen long into the future, but what they might find in the rivers later this summer when the water levels go down.
The most obvious benches are usually near the valley floor, but they can be thousands of feet above the valley floor. Since benches were made by streams, they can contain placer deposits.
Sylvester Smith and his younger brother Nathan were among this group who rode and led their Indian ponies, while climbing the rugged Salmon River breaks and rockhewn mountains, looking for a path that would lead them up and over the uncharted wilderness.
While a large number of locations have yielded some placer gold, most of the state’s placer production has come from a few productive districts.
