ASBESTOS IN THE UNITED STATES (Exclusive of Alaska and Hawaii)
By A. H. Chidester and A. F. Shride
Introduction
The asbestos deposits in the United States (ex clusive of Alaska and Hawaii) are shown on the accompanying map. The principal mineralogic types of asbestos (chrysotile and amphibole) are indicated by the shape of symbols, and the relative importance of the deposit is indicated by the size of symbols.
The text lists localities by State by numbers that are keyed to the map. Localities are distinguished by name of mine, prospect, or geographic area; their coordinates are given to the nearest minute of lati tude and longitude. Geologic relations of each occur rence, if known, are characterized briefly. The text and map were compiled from published and unpublished information, and at least one reference is given for each locality if reports on it have been published.
Chrysotile asbestos, a variety of serpentine, occurs chiefly in serpentinized peridotite and is dis tributed in the (Jflited States in two principal belts, the eastern extending from Maine to Alabama, and the western extending from Washington to California, where numerous masses of ultramafic rocks were in truded in Paleozoic and Mesozoic time, respectively. Domestic production from deposits of this type has not been large compared with that of Canada from the extensively developed deposits in Quebec, Ontario, and British Columbia. The principal mine in the United States is located at Belvidere Mountain, Vt. Minor amounts of asbestos have been produced from other deposits in these belts and from scattered occurrences of chrysotile elsewhere in a number of States between them. Increased exploration and de velopment activity for short-fiber chrysotile has recently been reported in California.
Chrysotile also occurs in bedded limestone, meta morphosed close to intrusions of diabase. The princi pal occurrences of this type are in Arizona, where small quantities of long-fiber, low-iron chrysotile have been mined from numerous small deposits.
Several species of amphibole occur in fibrous forms; in the United States only anthophyllite and tremolite are known to have commercial importance. As both the anthophyllite and tremolite occur in ultramafic rocks, associated greenstone, and amphibo lite, the overall distribution of amphibole asbestos in the United States is like that of chrysotile. The de posits are generally small and erratic in distribution.
