Which is older a gabbro dike or a gray shale?
A gabbro dike is typically older than a gray shale. Gabbro is an igneous rock that forms from the cooling of magma intruding into existing rock formations. Gray shale, on the other hand, is a sedimentary rock that forms from the accumulation of sediment over time. Therefore, the gabbro dike would have formed before the gray shale was deposited.
How can you tell that sandstone is older than a basalt layer?
If the sandstone is below the basalt layer, it is older. Though caution is advised, to make sure it is really a basalt layer and not an intrusion of gabbro. Other indicators that the sandstone is older is evidence of alteration to the sandstone where the two meet (called a "baked contact") and pieces of sandstone being found in the the basalt.
Is tan sandstone or brown sandstone older?
In general, sandstone does not have an inherent color based on its age. The color of sandstone is influenced by the minerals present in the rock. Age is determined by the formation process and the relative position of the rock layers in the Earth's crust, not the color of the sandstone.
How can you tell that the sandstone was not deposited on top of basalt layers?
The sandstone layer is older than the basalt. The older rock cannot be on top of the younger rock. The sandstone and the basalt (or basalt dike) are both deposited at the same depth.
How much gabbro is in olivine?
Olivine does not contain Gabbro. Gabbro can contain olivine. Usually no more than a few percent.
Which is older a gabbro dike or a gray shale?

When The walls of the grand canyon are made up of layers of sandstone a dike cuts across some of the layers when did the dike form?
The dike likely formed after the layers of sandstone, as it cuts across them. Dikes form when magma intrudes into existing rock layers and solidifies underground before being exposed at the surface through erosion. Therefore, the dike is a later geological event compared to the formation of the original sandstone layers in the Grand Canyon.
Is gabbro a dike?
