According to model, lead zinc ore bodies of mineral deposit, celestite ore bodies and gypsum ore bodies are distributed by the incomplete dome shape. The sandstone type ore bodies like a curved surface shape, is on the top, wide distribution, which like the top cover of a mushroom. The limestone breccia type ore bodies, under the sandstone type ore bodies, with mostly irregular vein shape, lens body shape, locate at the root of the mushroom. Gypsum and celestite ore bodies, accompanying with limestone breccia type ore bodies with the shape of vein, lens body, distribute under the sandstone type ore bodies.
根据模型显示,金顶矿床铅锌矿体、天青石矿体和石膏矿体呈不完整的穹隆状分布,砂岩型矿体在上,为曲面状,分布广,似一蘑菇的顶盖,而灰岩角砾岩型矿体分布局限,部分产于砂岩型矿体之下,多为不规则的脉状、透镜体状,构成蘑菇的根部;石膏和天青石矿体主要与灰岩角砾型矿体相伴产出,呈脉状、透镜体状,多分布于砂岩型矿体下部。

A schematic model was proposed to illustrate the occurrences of various lithologies and lithofacies associations. The erosional surfaces on siliciclastic mudstones, funnel-shaped structure, and the exhuming of massive cold-seep carbonates exposed might have been occurred concurrently during a tectonic unstable time in SW Taiwan. The deposition of fossiliferous mudstone interfingered with the conglomerate lithofacies, and represented the rapid facies transition from siliciclastic (non-carbonate) into carbonate environment.
综合岩相观察结果,建构一个符合台湾西南部更新世珊瑚礁与基底泥岩接触关系的沉积相模式;其中,基底泥岩顶部的不规则冲蚀面、充填碳酸盐胶结泥岩砾与碳酸岩烟柱的漏斗状沉积,以及块状冷泉碳酸盐岩的出露,可能均为区域地质构造活动时期所造成;至於与含化石泥岩同时沉积的砾岩相,可能均为基底泥岩在快速浅化的过程中所沉积,标志古环境由矽质碎屑快速转变为碳酸盐环境的过程。

Recently, a nearly E-W-striking, over 10 km long albitite zone has been recognized for the first time in the Lower Silurian Meiziya Formation in a Lower Paleozoic lead-zinc ore deposit concentration area of the Xunyang basin, South Qinling. It shows a conformable contact and gradational relationships with the country rocks and has thick-bedded and massive, banded, brecciated structures and fine and very fine equigranular and intraclastic textures. It is chemically characterized by enrichment in SiO2, Al2O3 and Na2O and is rich in the trace elements Fe and Mn and poor in the trace elements Co, Ni and Cu. Its ∑REE, LREE and HREE are lower than those of the country rocks and exhibit pronounced Eu depletion.
