disconformity; parallel unconformity
Geology term for a type of unconformity where the strata above and below are parallel, indicating a period of non-deposition or erosion without tilting.
A disconformity is observed in this area.
不整合 is the general term for unconformity; 平行不整合 specifies the parallel type.
傾斜不整合 (angular unconformity) involves tilted older strata, unlike the parallel strata in 平行不整合.
Compound of 平行 (parallel) and 不整合 (unconformity), a direct translation of the English geological term 'parallel unconformity' or 'disconformity'.
