Sedimentary - but itdoes not necessarily contain fossils to be sedimentary.
Imprints or impressions of such things as footprints or trails are generally referred to as trace fossils. Body impressions are called mold fossils, and molds that are filled in are called cast fossils.
Mount Hood has high silica levels so the lava is felsic (Mt. Hood's silica values are as high as 64%).
Basaltic lava has a low viscosity which means it is thin and runny so it flows easily and spreads out.(:

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
any rock that was formed by sediments like limestone, sandstone, and shale
It would necessarily be sedimentary rock, formed in a saltwater or freshwater environment, depending on the type of clam.
The bonds in a N type or a P type semiconductor depends upon the impurity added into it. For example a trivalent impurity is added then three bonds will be formed by each atom and it becomes a P-type semiconductor whereas if a pentavalent impurity is added then five bonds will be formed by each and every atom and it becomes a N-type semiconductor.
Fossils
Imprint fossils, Mineralized fossils, frozen fossils, fossils in amber, and cast fossils.
