Control Experiments for Underwater Cultural Relics Survey by Marine Geophysical of Acoustics

Marine geophysical acoustic methods are a powerful tool for high-precision, large-scale underwater archaeological relics investigations and research in the shallow water. There is a complex coupling relationship between the marine environment and the preservation of underwater cultural relics, which leads to great uncertainty based on the detection data to deduce the existence and distribution of underwater cultural relics. In the past 30 years, the controllable experiments of acoustic methods for underwater cultural relics show that different side-scan sonar systems have varied acoustic response. Multi-beam sonar can be used to study the temporal variation of underwater cultural relics, while shipwreck partially or totally embedded in seabed sediments can be detected by sub-bottom profile. The control experiment will increase the understanding of the acoustic response for different underwater cultural types. Control experiment on the underwater cultural relics can provide a reference for the correlation between detection results and interpretation accuracy, and hopefully provide a systematic solution for underwater cultural survey in an efficient way and on a wide-scale, thus better protecting and managing underwater cultural relics.     

赣南钨矿新类型及“五层楼＋地下室”找矿模型

赣南具“世界钨都”之称,特别是易识别、易选的石英脉型钨矿床闻名遐尔。近20年来,在开采开发石英脉型钨矿的同时,人们也发现了一种新的钨矿类型,即八仙脑式的破碎蚀变岩带石英脉复合型钨矿。本文通过对八仙脑钨矿成矿特征的研究,提出了“五层楼＋地下室”的找矿新模型,以期对该区的新一轮钨多金属矿找矿有所启迪与帮助。该模型已经对老庵里、金银庵等大、中型钨矿的勘探起了重要的指导作用。
