Nail Testing for Fungus (Onychomycosis) This test is used to detect and diagnose infections of the nail using a PAS stain. Place nail fragments in an empty sterile container 10% formalin. For containers and fixative, contact UF Health Pathology Laboratories' Client Services Department at 888.375.LABS (5227).
What is a tectonic plate? A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.
If one of the colliding plates is topped with oceanic crust, it is forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into new crust. Magma formed from melting plates solidifies into granite, a light colored, low-density rock that makes up the continents.Thus at convergent boundaries, continental crust, made of granite, is created, and oceanic crust is destroyed.Two plates sliding past each other forms a transform plate boundary. Natural or human-made structures that cross a transform boundary are offsetâsplit into pieces and carried in opposite directions.here are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This image shows the three main types of plate boundaries: divergent, convergent, and transform. Image courtesy of the U.S. Geological Survey.
