Question: What is SM Nd dating used for?

The Sm-Nd system is useful for determining crystallization ages of igneous and metamorphic rocks. It has proven especially valuable for dating mafic and ultramafic rocks that are, in general, difficult to date using other methods.The Sm-Nd system is useful for determining crystallization ages of igneous and metamorphic rocks.

What rocks are likely to contain fossils?

How do fossils form? Fossils are typically found in sedimentary rocks and occasionally some fine-grained, low-grade metamorphic rocks.

What type of rock are fossils most commonly found in?

sedimentary rock Most fossils hide out in sedimentary rock . When tiny bits of rocks and minerals (called sediment) join together over millions of years, they become sedimentary rock. Plants and animals that become sandwiched in this sediment eventually turn into fossils. Two examples of sedimentary rocks are sandstone and shale.

What are the three types of unconformities?

Commonly three types of unconformities are distinguished by geologists:ANGULAR UNCONFORMITIES.DISCONFORMITIES.NONCONFORMITIES.
