其中常见的种类是蓝藻、二氧化硅包裹硅藻、甲藻、绿藻和白垩涂层颗石藻。
Among the common kinds are cyanobacteria, silica-encased diatoms, dinoflagellates, green algae, and chalk-coated coccolithophores.
本文介绍了天然金刚石、天然刚玉、石榴石、石英、燧石、浮岩、硅藻土、赤铁矿、珍珠岩等天然磨料的性能特点和其应用。
This paper discusses the performance and application of natural abrasive such as diamond, corundum, garnet, quartz, flint, pumice, diatomite, hematite and perlite.
亮蓝色很有可能是颗石藻-浮游生物的一种，外壳是白垩色的，能反光，把海洋弄得绿中泛白。而暗绿色的则可能是硅藻。
The bright blue colors are probably from coccolithophores, a type of phytoplankton that is coated in a chalky shell that reflects light, turning the ocean a milky turquoise.

先锋硅藻土矿床，蛋白石含量低，烧失量高，但是，硅藻土矿厚度大，储量大，充分利用先锋硅藻土矿有深远的重要性。
Although the opal content of Xianfeng diatomaceous deposit is low and burning loss is high, its thickness and reserve are big, therefore, fully using this diatomaceous deposit is very imu...
