The mineral bastnäsite or bastnaesite is one of a family of three carbonate-fluoride minerals, which includes bastnäsite-(Ce). Bastnäsite is one of the largest sources of cerium and other rare earth elements. Bastnäsite has cerium, lanthanum and yttrium in its generalized formula but officially the mineral is divided into three minerals based on the predominant rare earth element. Mountain Pass, San Bernardino County, California.

Wet rough asphalt black bitumen road pavement surface abstract grunge texture close-up top view background banner.\nBitumen is a sticky, black, highly viscous liquid or semi-solid form of petroleum. In the U.S., it is commonly referred to as asphalt. It may be found in natural deposits or may be a refined product, and is classed as a pitch. Before the 20th century, the term asphaltum was also used.\nTarmacadam is a road surfacing material made by combining crushed stone, sand, and tar.

Agate is a microcrystalline variety of quartz, chiefly chalcedony, cryptocrystalline form of silica.  Although agates may be found in various kinds of rock, they are classically associated with volcanic rocks but can be common in certain metamorphic rocks. Most agates occur as nodules in volcanic rocks or ancient lavas where they represent cavities originally produced by the disengagement of volatiles in the molten mass which were then filled, wholly  by siliceous matter deposited in regular layers upon the walls.
