million years ago. In this area the fault dips from 45 to 72 <br /> degrees to the west and the west block has moved downward rela- <br /> tive to the east block. <br /> The Kokomo Syncline plunges to the north. Dips of the <br /> sedimentary beds are generally steeper on the eask flank of the <br /> syncline than on the west flank. A generalized cross-section of <br /> the syncline is shown in Appendix G. <br /> 4.2 GLACIATION AND EROSION AT CLIMAX <br /> Post-ore erosion and glaciation of the Climax deposit <br /> has caused the deposition of high grade molybdenite and associated <br /> minerals in detrital material over a large area to the north, <br /> west and south of Climax. T1).is material adds substantial amounts <br /> • of xolybdenite and associated products to the surface waters in the <br /> area. <br /> The ore bodies were emplaced at Climax approximately 30 <br /> million years ago. Reactivated movement along the Mosquito Fault <br /> took place in the range of 26 to 10 million years ago. This <br /> faulting moved the west block downwards relative to the east <br /> block and left the east block (containing the majority of Climax <br /> mineralization) as a topographically high area. Erosion and <br /> Pleistocene Glaciation then removed large amounts of material <br /> from the top of the east block. <br /> At least two stages of Pleistocene Glaciation advanced <br /> from the Climax area and moved down the Tenmile, Arkansas and <br /> Eagle Valleys. Figure 4. 1 shows that all but the root zones of <br /> 4-4 <br />
