海洋学院东方红号调查船于1981年6月在东海北部进行了综合海洋调查,并在38个实测站位采集了表层沉积样。我们在研究这些样品时,发现了具有泡壁结构的火山晶屑,晶屑主要为石英(图1)、长石(图2)及紫苏辉石(图3)。所谓泡壁结构,即在这些矿物的表面粘附了一层玻璃质包壳,由于玻璃具有气泡而使晶屑表面呈现多孔状外貌。这种结构国外虽已有报
In August 1981, the Dongfanghong survey vessel of the Ocean University conducted a comprehensive marine survey in the northern part of the East China Sea and collected surface sediment samples from 38 stations. When we looked at these samples, we found volcanic crystal fragments with bubble-wall structure. The main crystalline particles were quartz (Fig. 1), feldspar (Fig. 2) and peridotite (Fig. 3). The so-called bubble-wall structure, that is, the surface of these minerals attached to a layer of vitreous cladding, as the glass with bubbles so that the crystal surface appearance of porous appearance. Although this structure has been reported abroad
