PETROLOGIC DATA
Rock Number: 1
-interlayered sequence of massive, laminate crossbedded and faserkiesel rich grey feldspathic sands
-bedding is intensly Z-folded about west trending axes but grading indicates tops upright toward the south
-general trend of bedding is toward SE around 110 to 120 degrees
-axial planes of folds invaded by TL -rich egs.
-folding is to severe to be certain of be thicknesses but appear to be 30 to 60 cm
-cross bed features are distorted into almost random alignment of intersecting planes
-major z-folds are isoclinal and probably have an amplitude of 100+ m
-sporadic CLCC horizons with EP-HB-GR assembledge
-SAMPLE A massive
-SAMPLE B MV knot unit
