What granite intrusion crosses a thick sandstone bed which is older and what law is it?
The granite intrusion that crosses a thick sandstone bed is an example of an igneous intrusion that is younger than the sandstone. This relationship is explained by the Law of Cross-Cutting Relationships, which states that geological features that cut through other rocks must be younger than the rocks they cut through. Thus, the granite intrusion is considered younger than the sandstone bed it intersects.
What is the relative age of fault or igneous intrusion that cuts through an unconformity?
If a fault or intrusion cuts through an unconformity, the fault or intrusion is younger than all the rocks it cuts through above and below the unconformity.
What a cross cutting relationship?
Cross cutting relationships define rock formations in geology. When magma enters cracks and crevices in existing rocks and cools it forms what is called an igneous intrusion. The principal of cross cutting relationships means that the igneous intrusion is always younger than the rock it cuts across.
What is the relative age of a fault or igneous intrusion that cuts through an unconformity?
The relative age of a fault or igneous intrusion that cuts through an unconformity is younger than the unconformity but older than the rock it cuts through. This is because the fault or intrusion must have formed after the deposition of the rock layers below the unconformity but before the deposition of the rock layers above the unconformity.
According to the principle of cross-cutting relationships an intrusive rock body is?
According to the principle of cross-cutting relationships, an intrusive rock body is younger than the rocks it intrudes into. This is because the intrusion must be younger in order to squeeze into the pre-existing rocks.
Is an extrusion older or younger than the rock layer below it?
Extrusion is older than intrusion because, an extrusion is always younger than the rocks below it. An intrusion is always younger than the rock layers around and beneath it. Hope the answers correct ;)
What do an intrusion and an extrusion tell us about the rock layers?
(Intrusion) You can learn how old the rock layers are around it. the rock layers around under and all around the intrusion are always older than the intrusion itself. (EXTRUSION) the layers of rock bellow the extrusion is older than the extrusion.
Why are the rocks in a large igneous intrusion coaser grained than the rocks in a small igneous intrusion at the same depth?
The minerals had longer to form from the hot magma than did the minerals in the small intrusion, which would have cooled much faster.
What clue tells geologists intrusion?
A clue that tells geologists about an intrusion is the relationship between the rock layers. An intrusion is younger than the surrounding rocks it cuts through, so if the intrusion appears to cut across existing layers, it is likely an intrusion. Additionally, the mineral composition and texture of the intrusion can differ from the surrounding rocks, providing further evidence of an intrusion.
Is an intrusion younger than its surrouding rock layers?
An intrusion is younger than its surrounding rock layers. An intrusion needs another rock to cut through it, which is referred to as a cross-cutting relationship.
Why is an igneous intrusion younger than the rocks in which it is found?
An igneous intrusion is younger because it forms after the surrounding rocks have already solidified. Magma forces its way into the existing rock layers, and once it cools and solidifies, it is considered younger than the surrounding rocks. This relationship helps geologists determine the sequence of geological events.
What granite intrusion crosses a thick sandstone bed which is older and what law is it?
The granite intrusion that crosses a thick sandstone bed is an example of an igneous intrusion that is younger than the sandstone. This relationship is explained by the Law of Cross-Cutting Relationships, which states that geological features that cut through other rocks must be younger than the rocks they cut through. Thus, the granite intrusion is considered younger than the sandstone bed it intersects.
What is the relative age of fault or igneous intrusion that cuts through an unconformity?
If a fault or intrusion cuts through an unconformity, the fault or intrusion is younger than all the rocks it cuts through above and below the unconformity.
What a cross cutting relationship?
Cross cutting relationships define rock formations in geology. When magma enters cracks and crevices in existing rocks and cools it forms what is called an igneous intrusion. The principal of cross cutting relationships means that the igneous intrusion is always younger than the rock it cuts across.
What is always younger than rock layers around and beneath it?
A fault or an intrusion of magma is always younger than the rock layers around and beneath it. This is because faults cut across existing rock layers and intrusions of magma cool and solidify after the surrounding rock layers have already formed.
What is the relative age of a fault or igneous intrusion that cuts through an unconformity?
The relative age of a fault or igneous intrusion that cuts through an unconformity is younger than the unconformity but older than the rock it cuts through. This is because the fault or intrusion must have formed after the deposition of the rock layers below the unconformity but before the deposition of the rock layers above the unconformity.
When a granite intrudes into a layer of limestone which is younger granite or limestone?
When a granite intrusion occurs within a layer of younger limestone, the granite is considered older than the surrounding limestone. This is because intrusive rocks form before surrounding sedimentary rocks. If the intrusion occurs within older limestone, then the limestone is considered older than the granite.
