Dayton iron deposit, Lyon County, Nevada
TL;DRAbstract
The Dayton iron deposit, in Lyon County, Nev., was studied and explored in 19^2 "by the Federal Geological Survey and the Bureau of Mines. It is a con tact-me tamo rphic deposit in partly metamorphosed and folded sedimentary beds of unknown geologic age, which are intruded by granitic rocks. Most of the ore is on and near the crest of a southward-plunging anticline. Magnetite is the main ore mineral, and is accompanied by pyrite, epidote, garnet, and unreplaced minerals of the original rocks. Hematite and limonite have been formed near the surface. Exploration has revealed two bodies of ore in the main part of the deposit. The larger is an irregular lenticular "body near the crest of the anticline. The other, which lies farther north, is in steeply dipping rocks and is of unknown shape. Still farther north are scattered smaller bodies of ore.
