Samples collected from the East Fault consist mostly of what appears to be Mn-oxide cement and some samples have huge botryoidal Fe-oxide. Most of the botryoid samples that were collected come from float material because it was difficult to find good specimens in the outcrops. This fault was located using an old map used by miners prospecting for manganese in the 1940's and 1950's. There were a few other prospects on that map but due to limited time we were only able to go to one prospect.
Below you will find a few petrographic images and SEM images acquired from samples from this location along with descriptions. Note that the oxide identification for these samples is based solely on petrographic observations and have not been confirmed using SEM/EDS analyses.
