Exempel på hur man kan använda BATHOLITHS i en mening

• These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers.
• The areal extent of anorthosite batholiths ranges from relatively small (dozens or hundreds of square kilometers) to nearly , in the instance of the Nain Plutonic Suite or Mistastin crater in northern Labrador, Canada.
• Intrusive rock is formed when magma penetrates existing rock, crystallizes, and solidifies underground to form intrusions, such as batholiths, dikes, sills, laccoliths, and volcanic necks.
• 6 Ga by the emplacement of major granitoid batholiths that thickened and stabilised the continental crust during the early stages of an arc-related magmatism and sedimentation cycle.
• Individual plutons may cover several thousand square kilometres and these composite granitoid bodies have traditionally been referred to as batholiths, alluding to their compositionally and texturally heterogeneous nature and enormous areal extent.
• The immense volumes of magma involved in batholiths can force their way upwards only when the magma is highly silicic and buoyant, and are likely do so as diapirs in the ductile deep crust and through a variety of other mechanisms in the brittle upper crust.
• Batholiths and dikes were also exposed by erosion, such as the Timber Lake, Mulock, West Arm, Powassan and Bonfield batholiths.
• The Barberton Greenstone Belt is located on the Kaapvaal craton, which covers much of the southeastern part of Africa, and was formed by the emplacement of granitoid batholiths.
• West of the Nevadaplano stood the Sierra Nevada, which was volcanically active until 80 million years ago and featured exposed batholiths from former volcanism.
• Episodic construction of batholiths: Insights from the spatiotemporal development of an ignimbrite flare-up.
