boyakko [2]

The lower rocks in the Muav limestone are 505 million years old. The upper rocks in the Redwall limestone are 340 million years
Alex777 [14]

Unconformity

Explanation:

The gap between the lower and upper limestone layer can be explained by the occurrence of an unconformity.

An unconformity is a break in stratigraphic record usually marked a prolong period of non-deposition or erosion.

A major break of several millions of years is called a hiatus. A minor break is a diastem.

  • During a period of non-deposition, no materials are brought into the basin.
  • This can last for several years until deposition resumes again.
  • Such a prolonged period of non-deposition causes a break in stratigraphic record.
  • At other times, stratigraphic records can be lost to erosion.
  • Erosion entails the washing away of the earth.
  • This will ultimately cause the loss of records between two strata till deposition resumes.
  • In most strata, periods of non-deposition and erosion usually takes place hand in hand.
