petrified
Fossils formed when silica is added are called silicified fossils. Silica replaces the original organic material of the organism, resulting in a preserved fossil with a glassy appearance. This process can produce detailed and well-preserved fossils.
Sedimentary - but itdoes not necessarily contain fossils to be sedimentary.
no. AA has a relatively low silica content level.
Sedimentary rocks are the type in which fossils are most commonly found. This is because they are formed from layers of sediment, which can entomb and preserve the remains of plants and animals over time. Examples of sedimentary rocks where fossils can be found include limestone, sandstone, and shale.
Most fossils form in sedimentary rock, which is formed from layers of sediment that build up over time. This process preserves the remains of plants and animals, creating fossils.

A lamprophyre is a type of ultramafic intrusive igneous rock. It is very rare for fossils to be formed in igneous rocks (and they usually only form as mold fossils in extrusive deposits). As such fossils will not form in lamprophyres.

anion
Metamorphic rocks do not typically contain fossils, as the intense heat and pressure involved in their formation often destroy any remnants of organic matter. Igneous rocks are formed from molten material and do not contain fossils. Sedimentary rocks, which form from the accumulation and compression of sediments, are the type of rock that commonly contain fossils.

It would necessarily be sedimentary rock, formed in a saltwater or freshwater environment, depending on the type of clam.
Tertiary fossils are usually found in sedimentary rock layers. Sedimentary rocks are formed by the accumulation and compression of sediments over time, making them a common host for preserving fossils from the Tertiary period.
