Question
MINE2200-Winter 2018 Estimate the distance between Cassidy Lake and Halifax (use the black circles as kilometers reference)? What is the geologic unit that covers the south-Eastern shore, NS? How can you explain the absence of any fossils in this area? - - -If you are hunting for dinosaur fossils in the Maritimes, which area on the map you should look in (Hint: remember Jurassic Park)? What he geologic fations tht are No ecord n What is the least recorded geologic unit in New Brunswick? - What is the most dominant geologic unit in the Maritimes? Prince Edward Island New Brunswick Cassidy Lake Highlands Known Cretaceous occurrences Triassic-Jurassic 44" 100 km Carboniferous Pre-Carboniferous 65 4Explanation / Answer
1. The estimated distance between Cassidy Lake and Halifax is approx 200kms. We can estimate it from the scale given and the black dots.
2. The geological unit covering the south eastern shore of NS is Precarboniferous (white coloured unit indicates Precarboniferous- colour index).
3. We can see that the rock units of Pre-Carboniferous age, Carboniferous age and Triassic- Jurassic age occurs together. This cannot be possible without any kind of deformation taking place. So fossils are absent in this area.
4. We can get the dinosaur fossils in the Triassic-Jurassic times, that is the part of the map which is coloured dark grey.
5. Prince Edward Island comprises rock units of the Carboniferous age. It doesn't comprise rock units of Pre-Carboniferous and Triassic-Jurassic age.
6. The least recorded rock unit in New Brunswick is Triassic-Jurassic. It has rocks of Carboniferous age surrounded by Pre- Carboniferous age.
7. The most dominant unit in the Maritimes is the Pre- Carboniferous unit. (We can estimate it from the colour index).
