Quaternary Alluvium (Recent) <br />One alluvial deposit less than one meter in thickness <br />was located on the Carbon Junction Mine property. Some extensive soil profiles were <br />mapped and are discussed under the soils section. The U.S.G.S. (Zapp,1949) did locate <br />some alluvial deposits two miles northwest in the city of Durango and one mile south of <br />the mine area, and both were proximate to the Animas River. Some alluvial units which <br />appeared in the Johnson Report, 1982 were field checked and compared with U.S.G.S. <br />mapping. These units were found to be terrace gravels with good soil development. <br />General Structure <br />The Carbon Junction Mine lies on the north flank of the San Juan Basin. The steep dips <br />(30 degrees southeast) are a direct influence of the San Juan uplift to the north. Strike of <br />the beds in the mine area range between N40E and N50E averaging N45E. Relative <br />differences in the coal measures are a result of differential compaction and do not signify <br />Appendix 4-2a) <br />complex faulting or folding. See Cross Sections Ethrough N(for details <br />of the mine stratigraphy and structure. It should be noted that certain of the drill logs <br />enclosed are set on an unidentifiable coordinate system and, accordingly, could not <br />located on the geologic maps. These logs were enclosed for general lithologic <br />description and not used to compile the geology of the mine. Accordingly, they were not <br />used or shown on cross section and drillhole maps. These logs are included for <br />informational purposes only.
