| 中文摘要: |
| 文章阐述了新疆伽师铜矿床的地质特征,建立了矿床成因模式.铜矿体产于古近系灰白色含岩屑钙质细砂岩中,呈与地层整合的板状、层状;矿体和上盘围岩由于岩性不同接触界线比较清楚,二者为正常沉积接触关系;矿体和下盘围岩接触界线清楚,矿层底部常见有砂、砾岩质含矿体,二者为连续沉积及部分冲刷沉积接触关系.矿床成因类型应属古近纪湖相沉积层控型砂岩铜矿床. |
| 英文摘要: |
| Geological characteristics of Jiashi Cu deposit are discussed and the genetic model is established.Cu ore of the deposit occur conformably in fine paleogene grey white debris-bearing calcareous sandstone as tabular layed bodies.The ore body contacts more sharply with hanging wall due to variation of lithologies in continuous sedimentation and sharply with foot wall due to the common basal sandy,conglumeritic ore body.The sandy and conglumeritic ore bodies are in wash sedimentary contact.The Cu deposit should be a stratobound Paleogene lake sedimentary sandstone-hosted Cu deposit. |
