我认为,除了同生沉积加上成岩固结后改造、变质等因素以外,一个矿区的矿体呈层状似层状,能否就叫层控矿床,还需在其他矿区或在较大范围内也能找到同层位(或同一岩层组合)的矿体(矿化)即有“面”的、区域的找矿意义才行,否则可能是偶然的、局部的、只具描述性质的层状、似层状矿床。个旧锡矿在相邻几个矿田内,似层状矿体累计有十九个含矿层位,由于对比困难,外围又未找到相同岩层组合的矿化,因此,仍称“层间氧化矿”为宜,而不叫层控矿床。
In my opinion, in addition to the sedimentation of the same age and alteration and metamorphism after diagenetic consolidation, the orebody in a mine area is in the form of a layer-like layer and can be called a stratiform ore deposit. It needs to be deposited in other mining areas or in a larger area (Mineralization) in the same layer (or in the same rock formation) can also find “face”, and the prospecting significance of the region can be causal, otherwise it may be accidental, partial and only descriptive layer Like, like layered deposit. Gejiu Tin Mine in adjacent several ore fields, like stratiform ore body contains a total of nineteen ore-bearing strata, due to the comparison difficulties, the outer periphery and did not find the same rock formation mineralization, so it is still called “interlayer oxide ore” Suitable, not called stratabound deposit.
