The fault is either a (N,S,Ew) block moved seeing a cross section of the fault, it is not possible to determine if the fault is normal or (N,S,E,W) block. Without -aged strata. --aged strata are overlain at an unconformity by What type of unconformity is it? d) If you walk from left to right (west to east) along the southern edge of Map A, are you walking\"up section\" ks of progressively younger age) or \"down section\" (ie, into rocks of progressively older age)?
c) i. A SouthEast - NorthWest trending fault cuts strata that strikes in a NorthEast - SouthWest direction and dip to the NorthWest.
ii. The fault is either a oblique-slip fault or a dip-slip fault in which the W block moved down relative to the E Block. Without seeing the cross section of the fault, it is not possible to see whether the fault is normal or reverse.
iii. Devonian - aged strata are overlain at an unconformity by Cretaceous-aged strata.
It is an angular unconformity.
d) If we walk from left to righ i.e. from West to East, along rhe Southern edge of Map A, we are walking \"down section\" i.e. rocks of progressively older age. This is because we encounter Devonian strata (Devonian Tella Fm., Bouser Fm., Norfolk Fm.) before Silurian Strata (Silurian Hallo Fm.). Devonian is younger in age than Silurian.
