本文所述的矿带,位于某小型拗陷中,其中出露有早泥盆世至中三迭世地层。泥盆纪地层主要是灰岩、泥灰岩、页岩的互层;石炭纪至二迭纪地层为灰岩;中三迭世地层为页岩、砂岩、灰岩的互层。它们之间均为不整合接触。岩层总厚度大于7,000米。矿带内地层普遍受到了褶皱、错断的影响。发育有北西向紧密线型排列的短轴背、向斜,背斜常呈倒
The ore zone described in this article is located in a small depression, where the Devonian-Middle Triassic strata were exposed. The Devonian strata are mainly interbedded limestone, marl and shale; the Carboniferous-Permian strata are limestone; the Middle Triassic strata are interbeds of shale, sandstone and limestone. They are all unconformable contacts. The total thickness of the rock formation is more than 7,000 meters. The strata in the ore belt are generally affected by folds and faults.
