Question #0c575
1 Answer
A period of erosion or uplift followed by further sedimentation
Explanation:
A disconformity is usually determined by the types of fossils found in layers of sediment that are touching each other.
Often two sedimentary layers are found with fossils that have been assigned by Darwinian evolution ages that are vastly different. The layers lay on top of each other like they were laid down in sequence with little or no time difference between them.
The assumption that has been a time difference because of the index fossils is that subsequent layers either have been removed or prevented from being formed. The most common inference is that other layers had been laid down on top of the bottom layer and then eroded away. After the erosion then another layer of sediment was laid down on top of the now exposed bottom layer.
The explaining the frequent occurrence of disconformities is one of the difficulties facing uniform geology
