张家垭磷矿区发育地层为震旦系和寒武系白云岩，构造主要为单斜构造。磷矿体仅有一个，呈层状产于下震旦统陡山沱阶一段，沿走向延伸3460.62m，沿倾向延伸400～1400m，厚度0.59～2.34m，均厚1.70m。矿石自然类型包括泥质条带磷块岩、白云质条带磷块岩及块状磷块岩，工业类型均属混合型矿石，常量组分主要为P2O5、CaO及SiO2。成矿物质源于秦岭海槽，成矿作用包括温压变化、生物活动及化学结晶。主要控矿因素为沉积盆地的深度和广度，本区存在一定找矿前景。

Sinian and cambrian dolomite spread in Zhangjiaya ore district. Monocline is the major structure. There is only one phosphorite body, occurring in lower Sinian doushantuoan stage, trending to 3460.62m along the strike and 400~1400m along dipping direction with total thickness 0.59~2.34m and average 1.70m. The natural ore types contain argillaceous banded Phosphate rock, dolomitic banded Phosphate rock and massiveness Phosphate rock. Their industrial type belong to mixed ore which major components are P2O5、CaO and SiO2. Ore-forming materials derive from Qinling ocean trough. Mineralization contains thermobaric variation, biological activity and chemicrystallization. The major metallotects are the depth and breadth of the sedimentary basin. There is certain perspective for prospecting in this area.
