頁(yè)巖(Shale),是一種沉積巖,成分復(fù)雜,但都具有薄頁(yè)狀或薄片層狀的節(jié)理,主要是由黏土沉積經(jīng)壓力和溫度形成的巖石,但其中混雜有石英、長(zhǎng)石的碎屑以及其他化學(xué)物質(zhì)。用硬物擊打易裂成碎片。抵抗風(fēng)化的能力弱,在地形上往往因侵蝕形成低山、谷地。頁(yè)巖不透水,在地下水分布中往往成為隔水層。形成于靜水的環(huán)境中,泥沙經(jīng)過(guò)長(zhǎng)時(shí)間的沉積,所以經(jīng)常存在于湖泊、河流三角洲地帶,在海洋大陸架中也有頁(yè)巖的形成,頁(yè)巖中也經(jīng)常包含有古代動(dòng)植物的化石。
Shale, or Shale, is a sedimentary rock of complex composition, but with thin or laminar joints. It is mainly rock formed by clay deposition under pressure and temperature, but it is mixed with fragments of quartz, feldspar and other chemicals. Strike with something hard and easily break into pieces. The ability to resist weathering is weak, and often forms low mountains and valleys due to erosion on the topography. Shale is impermeable and often becomes a water-barrier in groundwater distribution. Formed in the environment of still water, sediment after a long time of deposition, so often exist in lakes, rivers and deltas, there is also the formation of shale in the continental shelf of the ocean, shale also often contains the fossils of ancient plants and animals.
