How does sandstone form in offshore environments?Most quartz forms in either igneous rocks or environments with geothermal waters. In igneous rocks, quartz forms as magma cools. Like water turning into ice, silicon dioxide will crystallize as it cools. Slow cooling generally allows the crystals to grow larger. Quartz that grows from silica-rich water forms in a similar way.Quartzite forms when pure or nearly pure quartz sandstone undergoes intense heating and pressure usually related to tectonic compression. Geologically speaking, quartzite formation involves two types of metamorphisms: contact and Barrovian. Quartzite can form by either or both of these processes. 1.How does sand form?
