if gabbro cut across sandstone and schist and schist is the oldest meaning the bottom layer of sediment would the gabbro be the youngest layer im getting really mixed up ive searched on the web for a diagrame but they show intrusions of all kinds i need help in finding a diagrame and can u give an insight into a history of the region starting with the schist i would be greatfull for any help
You should read articles by Dr. Ken Ham. He is an expert on this subject.
Jane I'm struggling on this too!
and me too i thought this wouldnt be too hard a course for a level one lol
I understand that you're looking for a diagram and some insights into the geologic history of a region involving gabbro, sandstone, and schist. Since I cannot browse the web or provide specific articles by Dr. Ken Ham, I can help explain how you can approach finding the information you need.
Finding a diagram:
1. Start by searching for "geological cross-section diagram" or "geological history diagram" related to the specific region you're interested in.
2. Specify the region name or geological formation names in your search to narrow down the results.
3. Explore websites of reputable geological organizations, universities, or academic journals as they often have relevant diagrams available as resources.
Understanding the geologic history:
1. Begin by understanding the basic principles of stratigraphy, which study the layers of rock and their relative ages.
2. Given your context, sandstone and schist are both sedimentary rocks, while gabbro is an igneous rock.
3. Schist being the oldest means it was formed first and should be at the bottom in the sequence of rocks.
4. Gabbro, being an intrusion, would have intruded into the pre-existing sandstone and schist layers.
5. Use the principle of superposition, which states that in an undisturbed sequence of rocks, the oldest rocks are found at the bottom.
6. Analyze other geological structures, such as faults, folds, and unconformities, which may further impact the arrangement and order of the rocks in the region.
Tips for understanding geology courses:
1. Consult your textbook or course materials for explanations of the key concepts.
2. Reach out to your professor or teaching assistant if you're struggling to comprehend certain topics.
3. Form study groups with classmates to discuss and clarify misunderstandings.
4. Seek additional resources such as videos, online lectures, or academic papers to supplement your learning.
Remember, while I cannot provide the specific information you requested, these tips should help you in finding the diagram and understanding the geologic history related to your question.
