In the case of a credit card/cash advance, there's also the convenience of not having to go through a new loan application process and having the funds almost immediately. As noted above in the government home improvement loans section, the Title 1 program also allows unsecured loans of $7,500 or less.
Intrusive Igneous Rocks. Intrusive, or plutonic, igneous rocks form when magma cools slowly below the Earth's surface. Most intrusive rocks have large, well-formed crystals. Examples include granite, gabbro, diorite and dunite. Mineral Photos courtesy of R.Weller/Cochise College.
Examples of intrusive igneous rocks are diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass. These rocks include andesite, basalt, obsidian, pumice, rhyolite, scoria, and tuff. Pictures and brief descriptions of some common igneous rock types are shown on this page. Diorite is a coarse-grained, intrusive igneous rock that contains a mixture of feldspar, pyroxene, hornblende and sometimes quartz.
