Abstract

Abstract

Beiyi orebody and Nanliu orebody are the two main orebodies of Shilu iron deposit in Hainan Province, with high research value, ore-bearing wall rocks being the diopside-tremolite rocks and iron ores being mainly composed of hematite and tiny magnetite. By studying geochemical characteristics of wall rocks and ores of two orebodies and comparing their material composition differences, we hope that it could provide some useful information for prospecting in depth and periphery of deposit. Two orebodies have pronounced differences. The distribution patterns of main elements and trace elements of Beiyi's and Nanliu's high-grade Fe ore samples of two orebodies are pronounced; except that CaO and Co of Beiyi orebody's diopside-tremolite rocks are less than Nanliu orebody's, the remaining oxides and trace elements are more than Nanliu samples'. Beiyi orebody's diopside-tremolite rocks and high-grade Fe ores have weak Eu negative anomaly, and Nanliu orebody's iopside-tremolite rocks and high-grade Fe ores have Eu positive anomaly, and all samples have the characteristic of weak Ce negative anomaly and LREE depleted and HREE enriched relatively. It reflected that metallogenic environments or late hydrothermal fluid affected of two ore bodies are different.
