本工作区位于钦州市东南沿海,东起大风江口,西至钦州湾东北海岸。东、西部为滨海平原,中部剥蚀侵蚀台地濒临海岸,北面为起伏较大的丘陵。调查区内有海滨钛铁矿富集地带。为了解本区钛铁矿的储量,查清重矿物富集与地层之间的关系,我们分别在几道沙堤——泻湖布设了8个砂钻和13个钻孔(图1),用此来揭示全新世地层,并对岩心进行了微体古生物、重矿物、粒度等分析。本文主要根据这些钻探资料编写而成。 The work area is located in the southeast coast of Qinzhou City, east of the mouth of the typhoon, Qinzhou Bay, northeast coast. East and west of the coastal plains, the central erosion erosion platform near the coast, north of the larger hills. Survey area has a seafront ilmenite enrichment zone. To understand the reserves of ilmenite in this area and to find out the relationship between heavy mineral enrichment and stratigraphy, we arranged 8 sand drills and 13 boreholes on several sand dike-lagoons respectively (Figure 1) This reveals the Holocene strata and analyzes the core microfacies paleontology, heavy minerals, grain size and so on. This article is based on these drilling data.
