宋老伯说他现在很迷惘，不知道为什么千里之外的人如此的关心那散布原始山谷粘土中的金黄微粒。
Mr. Song said he was perplexed why people far from China were so eager for the golden flecks of rare earths that dot the clay of his formerly pristine valley.
这些沉积物富含粘土，粘土是由水流将岩石侵蚀成细小的微粒所形成的。
The sediments are rich in clay, which forms when water weathers rocks into fine-grained particles.
并提出了预防微粒运移技术对策，重点对粘土稳定剂的防膨长效性评价方法进行了探讨性的试验研究。
The countermeasures are proposed to prevent fine-grain migration. The experimental study is conducted emphatically for the evaluation method of anti-swelling durability of clay stabilizer.
胶体微粒可很容易地放入悬浮体中，但从悬浮体中沉降的速度慢于粘土颗粒大小的物质。
Colloids are easily put in suspension but settle out of suspension slower than clay-sized material.
