板巖(或稱板石)原巖主要是泥質巖、泥質粉砂巖和中酸性凝灰巖。重結晶不明顯,鏡下可見有泥質和部分絹云母、綠泥石、硅質,有時見少量的白云母、黑云母、石英等。具變余泥質結構。板巖是區域變質作用的產物,溫度和均向壓力都不高,主要受應力作用的影響,沿板理可以剝成薄片。板巖可以作為建筑材料、裝飾材料、高檔家居用品材料和工藝品,它具有重量輕、石質堅硬、耐酸堿、耐腐蝕、耐壓、抗風化、隔熱、隔水等特點。經久耐用,物美價廉,自然美觀。是一種低碳環保的新型建筑材料,使用年限在70年以上。
he protolith of slate or slabstone as called sometimes is composed of mainly mudstone, argillaceous siltstone and moderately acidic tuff, whose recrystallization is not obvious and
mudstone, sericite, chlorite, silica in parts, sometimes a small amount of muscovite, biotite and quartz are visible in it through a microscope. It features a blastopelitic texture. Actually, slate is a product of regional metamorphism, at moderate temperature and isotropic pressure, mainly subject to the stress. It can be sliced along its texture. Slate is widely used as a building
material, for decoration purpose or as upscale household items or crafts, because it is light, hard and highly resistant to acid, corrosion, pressure, weathering, heat and water as well as
durable, beautiful while affordable. It is a low-carbon environment-friendly building material with a service life of 70 years or longer.
