Clasts
Pebbles (in a conglomerate)
Geodes
Those ball-like objects are known as concretions and they form when minerals precipitate around a central nucleus. In the case of quartz concretions, silica-rich fluids flow through sedimentary rock layers and deposit quartz around a nucleus like a shell or fossil, forming the spherical shape. Concretions can come in various sizes and shapes and are often found in sedimentary rocks.
No, quartz is not clastic. Clastic refers to sedimentary rocks made up of broken fragments of minerals and rock material. Quartz is a mineral composed of silicon and oxygen, and it can be found in various types of rocks, including igneous, metamorphic, and some sedimentary rocks.
Quartz is mostly found in igneous and metamorphic rocks, such as granite and gneiss. It is also commonly found in sedimentary rocks, such as sandstone. Additionally, quartz can be found in hydrothermal veins and geodes.
Quartz can be found in igneous rocks when it crystallizes from molten magma during the cooling and solidification process. In sedimentary rocks, quartz can be present as a result of weathering and erosion of pre-existing rocks, with the quartz grains being deposited and compacted over time to form sedimentary rocks like sandstone.
Quartz typically forms in igneous, metamorphic, and sedimentary rock environments. It is commonly found in veins and pegmatites in igneous rocks, as well as in hydrothermal veins in metamorphic rocks. In sedimentary environments, quartz can be found in sandstone and shale formations.

Quartz is a mineral not a rock. Fossils can be found associated with quartz in sedimentary rock not inside the quartz.
Geodes are hollow ball-like objects found in sedimentary rocks that contain quartz crystals. These formations are typically created through the deposition of minerals within cavities in the rock over long periods of time. Geodes are often prized for their unique and beautiful crystal formations.
Quartz can be found in many places around the world, including Brazil, Madagascar, the United States, Russia, and India. It is one of the most abundant minerals on Earth and can be found in a variety of geological settings, such as igneous, metamorphic, and sedimentary rocks.

The hollow ball-like objects are called geodes. Geodes form when minerals are deposited inside cavities in sedimentary rocks, such as limestone or shale. The outer shell of the geode is typically made of chalcedony, while the interior can contain various minerals like quartz, amethyst, or calcite.
Quartz (SiO2) crystallizes from magma that is high in silica, thus most quartz is originally igneous. It then weathers out of igneous rocks as a clast and is deposited in what becomes a sedimentary rock. The original igneous rock or the quartz containing sedimentary rock can then become metamorphosed. Furthermore, quartz can also form out of solution by meteoric water or hydrothermal systems in which case it is a precipitate. It can be both crystalline or amorphous.

Geodes. They can be found in some igneous rocks as well. They start as a hollow cavity created by a gas bubble or decaying organism. Mineral rich water seeps into the cavity and crystals form from the outside toward the inside.
