摘　　要：文章通过对柬埔寨腊塔纳基里省中国墙矿区地质工作的分析研究,将该矿区矿化蚀变特征和典型的斑岩型矿床蚀变特征对比,认为该矿区属于斑岩型铜钼矿床。矿区蚀变横向上可划带分为石英绢云母蚀变、泥质蚀变和硅化(钾化)蚀变三个带。纵向可划分为钾化带、石英绢云母带和硅化带三个蚀变分带。金矿(化)体主要赋存于石英绢云母带上部或氧化带,现已剥蚀殆尽。铜钼矿(化)体赋存于石英绢云母带和钾化带过渡带或石英绢云母带的下部。According to the analysis and research of geological work in China Wall prospect in Ratanakiri, Cambodia, this paper compares the alteration in China wall prospect and the alteration of classic porphyry system, recognizing the deposit type in China Wall as porphyry copper-molybdenum deposit. The alteration in China Wall is composed of three zones laterally, phyllic alteration,argillic alteration and silicified(potassic) alteration, respectively. The alteration also contains three zones vertically, which are potassic,phyllic and silicified zones. Gold mineralization mainly distributes in upper part of phylilc alteration zone or oxidized zone, and is almost weathered to the end. Copper-molybdenum mineralization mainly distributes in phyllic zone or the transition of potassic and phyllic zone.
