nd leaching effect made residual material enrichment, and below it may produce leaching material enrichment. So the diving depth is moderate, the deposition of the rock and leaching, favorable for the formation of weathered ore deposit. (5) Geological structure. Big fissure zone and fracture zone, and determine the position of weathering deposits and extending direction, but also control the depth of weathering deposits. Tectonic movement also affect the preservation conditions of weathering deposits, weathering deposits on the structural lung area vulnerable to erosion, weathering deposits are buried in subsidence area, only in the case of small settlement, weathering deposits can be covered and preserved. (6) Time weathering deposits both scale and quality, take a long weathering deposits, mostly in the tertiary, quaternary or Mesozoic of the earth39。 s crust development around the world are not pletely consistent, their weathering deposits forming time is different, but they are late in all previous crustal movement, formed in a stable platform. 2 Types of ore deposits Weathering deposits according to the morphology of ore deposit can be divided into deposit along the surface of the earth39。 s surface development type, linear deposits along the rock broken zone and along the contact surfaces of the two kinds of rock contact type by weathering profile and its forming mechanism can be divided into the top of the crust of weathering eluvial placer deposit, diving residual ore deposit and dive below the surface on the surface of the the eluvial placer is physical weathering products, and its characteristics and other metallogenic regularity and causes of the placer deposit (see sedimentary deposit), and therefore can be classified as placer deposit. 3 The residual deposit Surface after chemical weathering and biological weathering rock, part of the material was leached, and the other part of the residual accumulation in the weathering crust of deposits, also known as residual ore residual substance is stable under the condition of the 6 surface of the earth, including iron and aluminum is the most stable, after weathering as iron ore and bauxite in the upper crust of weathering mineralization and , phosphorus, manganese and cobalt, nickel, copper, uranium, vanadium is a bit poor stability, in other conditions favorable, can form oxides, phosphate and other stable oxygen salts as residual ore deposit. Has the following several important residual ore deposit (1) Red clay type iron ore rock in hot, humid area after a strong weathering leaching effect, magnesium and silicon are groundwater away from the rock, most low iron into high iron, high water cut of formation of refractory iron oxide, and then dehydration int。
