沥青反射率BRo反映了沥青的形成受热作用影响不大,BRo大小实际上反映生物降解程度的强弱,志留系沥青砂岩主要是由较强烈的生物降解作用而造成的。
The asphalt reflectance ( BRo ) shows that formation of the asphalt was hardly affected by thermal action . Practically , the Silurian asphaltic sandstones were formed mainly by intense bio degradation and the BRo value reflects the bio degradation grade of the asphalt .
