| 中文摘要: |
| 闽西南-粤东海西-印支断陷带是我国华南重要成矿带之一,盛产铁、硫多金属矿床.龙凤场硫多金属矿床是其中较典型的代表,对其成因认识不一.经研究认为应属海底火山热泉沉积-迭加改造复合型矿床. |
| 英文摘要: |
| Based on the study on geology, geochemistry, petrochemistry, organic carbon, rare earth elements, trace elements and C, O, S isotopes, it is believed that Longfengchang sulfur and polymetallic ore deposit belongs to the Hereynian strata-bound marine volcanic hot spring ore deposit. The metallogenic hydrothermal solution is mainly composed of circling seawater and underground water and ore-forming elements substantially derived from the bottom strata. This deposit is strictly limited within the middle-lower Carboniferous Jinshe group (C2j) and Lindi group (C1l). It can be taken as an ancient example of marine hot spring ore deposits that occur widespreadly in Red Sea and East Pacific Ridge presently. There are three considerations in looking for this type of deposit, i.e. the tectonic setting, the middle-lower Carboniferous strata and the rock association. |
