SPURR MONOGRAPH <br />where it becomes very thin in the Smuggler mine and <br />disappears as a continuous sheet in the southern part of the <br />Della S. mine. <br />Igneous dikes, p. 51. Vertical dikes connecting with the <br />porphyry, probably from a hidden igneous body in the deep <br />subsurface, are found on Aspen mountain and on Smuggler <br />mountain, in among other locations the Smuggler mine. <br />Silver fault, p. 72. The Silver fault cuts out the blue <br />limestone' north of the Roaring Fork River. <br />Structure of Smuggler mountain, pp. 74-76, primarily as <br />exposed in Mollie Gibson and Smuggler mines, as follows: <br />Silver fault, p 74. The Silver fault is found <br />throughout Smuggler mountain, marked by a heavy breccia <br />zone' with shale [Belden] on the west, or upper, side, <br />and Leadville [Red Cliff Dolomite Member] on the lower <br />or east side. <br />Della and Smuonler faults, pp. 74-75. These are <br />relatively prominent east-west faults dipping south at <br />about 30°; there are others of the same trend [such as <br />the Emma] with less displacement, and are less easily <br />traced. This fault system is very significant in regard <br />to ore deposition, with the largest and richest ore <br />bodies at intersections of these faults with the Silver <br />fault s <br />Clark fault, pp. 75-76. The Clark fault displaces the <br />ore bodies and older structures, and is therefore a much <br />later fault.b <br />Description of geology and mining, pp. 180-188. The Mollie <br />Gibson and Smuggler mines are described, as follows:' <br />' Castle Butte Limestone member of the Leadville Limestone. <br />' Essentially breccia I and breccia II; see generally R.
