Paperback. 16pp. INTRUSION, estates, torts. When an ancestor dies seised of an estate of inheritance expectant upon an estate for life, and then the tenant dies, and between his death and the entry of the heir, a stranger unlawfully enters upon the estate, this is called an intrusion.

If not assimilated, it eventually resolidifies as the Muskox intrusion there are two chromite-rich layers, each occurring in a stratigraphic unit showing the layer sequence. intrusion 1. Geology a. the movement of magma from within the earth's crust into spaces in the overlying strata to form igneous rock b. any igneous rock formed in this way 2. Property law an unlawful entry onto land by a stranger after determination of a particular estate of freehold and before the remainderman or reversioner has made entry Intrusion a.   Maybe you are referring to intrusions of igneous material from the mantle (or from a subducting plate sliding into the mantle. Intrusions are typically granite or related materials, or basalts. They come up from the mantle through the surroundin.

Interpreting Geologic Sections This section includes two intrusions. An intrusion is produced when liquid magma is forced through existing rocks. An intrusion may force its way to the surface, and erupt as a volcano with lava flows, or it may remain entirely underground. When an intrusion cuts across pre-existing strata (a dike), it is pretty. The first part of this book presents reviews and new views of processes producing the textural, mineralogical and geochemical characteristics of layered igneous rocks. The second part summarizes progress in the study of selected layered intrusions and their ore deposits from different parts of the world including Canada, Southwest China.   Spinel occurs in the pyroxenitic, peridotitic and gabbroic layers of the Ivrea-Verbano layered igneous complex. Its composition varies between picotite and Mg-hercynite. Maximum Cr2O3 contents are found in the spinels of the dunitic cumulitic layers occurring at some height above the base of the complex. Chromium deposits are absent. The lack of chromite and of chromium deposits is Cited by:
