Sandstone.
Sand on beaches came from RIVERS.
Yes, quartz is a common mineral found in sand on riverbeds and beaches. It is one of the most abundant minerals in the Earth's crust and is highly resistant to weathering, making it a prevalent component in sand deposits.
Sand - is the name given to the microscopic grains of rock - that started out as cliffs or islands - and have been ground and pummelled by the action of the waves. You'll find large deposits on most beaches !
The beaches with black sand are volcanic in origin.
Sand
The removal of sand from beaches has been taking place in many Caribbean islands for decades. In the past, however, the volumes removed were relatively small. As populations and economies have grown in the region and construction materials have changed from wood to concrete, so too has the demand for sand. There are insufficient accessible, inland deposits of sand to satisfy demand. As a result, legal and illegal sand mining along beaches and shorelines, as well as in rivers, has increased. Remote beaches with road access are often targets for illegal mining.

beaches form with sand and water
Beaches are formed by waves depositting sand.
A sand deposit is a natural accumulation of sand particles, typically formed by the erosion and weathering of rocks over time. These deposits can be found in various environments, such as riverbeds, beaches, deserts, and deltas. They often vary in size and composition, influenced by factors like wind, water flow, and geological processes. Sand deposits are significant for various uses, including construction, glass manufacturing, and as habitats for certain wildlife.
Deposits of sand at the ocean's edge widen beaches and coastal areas by accumulating material carried by waves and currents. This process, known as sediment deposition, occurs when water slows down and loses energy, allowing sand particles to settle. Over time, these deposits can create wider shorelines, enhancing habitats for various marine and terrestrial species while also influencing coastal erosion and landscape changes.
