Sequential Basal faults in devonian dolomite, nopah range, death valley area, california.
Dolomite crystals from the Lost Burro Formation (Devonian) in the Nopah Range, eastern California, display basal stacking disorder as evidenced by transmission electron microscopy. Satellites in electron diffraction patterns indicate that stacking of anions and cations is different from that in ideal dolomite. This example conforms to the model of basal defects proposed by Goldsmith and Graf in 1958 to explain nonstoichiometry in dolomite. This dolomite from the Nopah Range was formed by deep burial replacement of micritic limestone, and its peculiar superstructure is tentatively attributed to the late diagenetic conditions during replacement.
