笔者认为,除了同生沉积加上成岩固结后改造、变质等因素以外,一个矿产地的矿床(包括层状,似层状矿体),能叫层控矿床者,还须具备下述条件:即在较大范围内也能找到同层位或同一岩层组合的矿床或矿化,即有“面”的、区域的成矿性才行;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,累计十九个含矿层位有似层状矿体,但由于对比困难,外围又还未找到相同岩层组合的矿化,一般仍称“层间氧化矿”而不叫层控矿床。
The author believes that in addition to sedimentation with the addition of diagenetic consolidation transformation, metamorphism and other factors, a mineral deposits (including stratified, stratified ore body), can be called stratabound deposit who must have the following conditions : That is, the deposits or mineralization of the same strata or the same rock formation can also be found in a relatively large area, that is, the “face”, the area of mineralization; otherwise it may be by chance, partial, only described Lamellar stratiform deposit. Gejiu tin mine in several adjacent ore fields, a total of 19 ore-bearing strata bit like layered ore body, but because of the contrast difficulties, the periphery has yet to find the same combination of mineralization rock formation, generally still called “interlayer oxide ore ”And not called stratabound deposit.
