| 中文摘要: |
| 户县大石沟碳酸岩，多年来一直被认为是超基性岩—碳酸岩杂岩体的一部分，属岩浆成因。在岩体地质及岩石学研究的基础上，通过微量元素、岩石化学、稀土元素及碳氧同位素分析，认为该岩石属构造—热液成因的交代蚀变碳酸盐岩。 |
| 英文摘要: |
| For many years,it has been suggesting that Dashigou carbonatite rock body is one part of the ultrabasic rock carbonatite rock complex bodies and it is formed by magmatic processis.The studies on the rock body's geology and petrology,analysis of minor elements, petrochemistry, rare-earth elements and carbon-oxygen isotope showed that the carbonatite of Dashigou is replacement-altered carbonate rock formed by tectonic process and hydrothemal activity. |
