| 摘 要： | 合肥盆地地球化学空间场属低背景、低湿度和非均匀场范畴。烃类指标浓度在盆地周边高、中间低。化探异常总体上表现为东强西弱、南北分带,异常上方三维荧光图谱以B型为主、P型次之,与轻质油、煤成烃特征相对应。从地球化学角度建议合肥盆地下一步勘探工作应继续采用综合勘探手段,重点解剖吴山庙—双墩集、桃溪—三河、曹庵—朱巷—白龙镇等不同类型的化探异常。

| Abstract: | The geochemical field of the Hefei Basin belongs to that of low background values, low moisture and inhomogeneity. The concentration of hydrocarbon indexes is high on the periphery of the basin and low in the middle. On the whole, the geochemical anomalies are strong in the east and weak in the west, and zoning in the south and the north. 3-D fluorescence diagrams of the samples within the anomalous zones mainly belong to type B, with type P following it.This corresponds to the characteristics of light oil and coal-formed hydrocarbon. From the geochemical view, the next exploration work was suggested to continuously apply the integrated exploration technology to explain the various kinds of geochemical anomalies on the key areas of Wushanmiao-Shuangdunji, Taoxi-Sanhe and Caoan-Zhuxiang-Bailongzheng. |
