This is a nonconformity. the contact is between an igneous and sedimentary rock formation. Granite should be on the bottom and sandstone on top, If this is not the case then some type of over-turning has taken place. The depositional envornment allowed sand to acculate over the top of the granite and later consolodated into a rock. This is called a contact. Many years ( perhaps millions) passed) before the whole mass became a rock formation. Can you identify other contacts in the area? If so, you may be able to date this contact and correlate it to other areas in your vicinity. See if you can trace it and look on geologic maps to see if it is mapped. If not, you may have found something that no one has yet discovered.

When granite and sandstone come into contact, the granite is usually the intrusive rock that has cooled beneath the Earth's surface, while the sandstone is the sedimentary rock formed from compacted sand grains. The contact between them is known as an intrusive-extrusive contact. This contact can lead to metamorphism in the sandstone due to the heat and pressure from the granite intrusion.

How is Granite different from Sandstone?
Granite is an igneous rock formed from the cooling of molten magma deep within the Earth's crust, characterized by its interlocking crystals of minerals like feldspar, quartz, and mica. Sandstone, on the other hand, is a sedimentary rock composed of sand-sized mineral particles and rock fragments, usually cemented together by minerals like quartz or calcite. Granite is more durable and resistant to weathering compared to sandstone.
What type of stone are the pyramids made of?
The pyramids in Egypt are primarily made of limestone blocks, with some parts constructed using granite and sandstone. The limestone was quarried locally and the granite was transported from Aswan, about 500 miles away. Sandstone was also used for some of the outer casing stones.
Can people sell stone?
Yes, people can sell stone in the form of raw materials such as granite, marble, or sandstone, as well as finished goods like sculptures, countertops, and tiles. Stone is commonly bought and sold in the construction and landscaping industries for various projects.
Where was granite mined in Canada?
Granite in Canada is mined in various locations, including Quebec, Ontario, British Columbia, and Nova Scotia. Each province has specific regions known for granite mining due to the high quality and quantity of granite deposits.
What are the granite mines in zhytomyr Ukraine?
Some of the granite mines in Zhytomyr, Ukraine include Korostyshev Quarry and Khoroshevsky Quarry. These mines produce high-quality granite used in construction, monuments, and other applications. The granite mining industry in Zhytomyr plays a significant role in the local economy.
A layer of sandstone is in contact with a mass of granite The granite contains small pieces of the sandstone Which rock is older?
The Granite
Which two kinds of adjoining bedrock would most likely have a zone of contact metamorphism between them?
shale and sandstone
If a mass of granite is in contact with a layer of sandstone that contains small pieces of the granite which rock is older?
granite
If a layer of sandstone is in contact with a mass of granite that contains small pieces of the sandstone which rock is older?
granite is older, Granite goes back more than 300 mya to the Ancestral Rockies or the first Rocky Mountains-Fountain Formation
How does change granite into sandstone?
Granite becomes Sandstone when water erodes the Granite on Earths surface, and then deposits the sediment.
Describe how the granite of a mountain could change first into sandstone and then into quartzite?
Weathering causes the granite to break down into small particles - sand. The sand becomes buried and compacts into sandstone. If the sandstone continues to be buried and comes into close contact with high heat, such as magma, it can be turned into quartzite.
Is sandstone a scoria granite or pumice?
None of those. Scoria, Pumice and Granite are igneous rocks. Sandstone is sedimentary.

Is the great wall of China made of granite or sandstone?
granite
What is the daughter rock of granite?
it is sandstone
Which rock is more porous granite sandstone or slate?
Granite particles are interlocked as the minerals formed from the slow cooling of molten material. Sandstone does not have the same interlocking crystal system, and voids between particles are generally larger.
Which rock holds more water shale sandstone or granite?
granite
