Latite is an igneous, volcanic (extrusive) rock, with aphanitic to porphyritic texture. Its mineral assembly is usually, alkali feldspar and plagioclase (in a ratio < 1:4). Quartz is absent. Biotite, hornblend, pyroxene and scarce olivine are common accessory minerals. Volcanic rock on North America Plutonic rock on North America Igneous rocks are formed when molten rock (magma) cools and solidifies, with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks. ... Extrusive refers to a mode of igneous rock formation, in which hot magma from inside the Earth flows out (extrudes) onto the surface. ... Bold text --202. ... An aphanite is an igneous rock with a fine-grained structure. ... (For other meanings of Porphyr, see Porphyry) The baptismal font in the Cathedral of Magdeburg is made of rose porphyry from a site near Assuan, Egypt Porphyry is a very hard red, green or purple igneous rock consisting of large-grained crystals, such as feldspar or quartz, dispersed in a... This article is about minerals in the geologic sense; for nutrient minerals see dietary mineral; for the band see Mineral (band). ... Feldspar is the name of an important group of rock-forming minerals which make up perhaps as much as 60% of the Earths crust. ... Plagioclase feldspar Plagioclase feldspars are a very important group of igneous rock forming tectosilicate minerals. ... Quartz is the second most abundant mineral in the Earths crust. ... A Biotite slice Biotite is a common phyllosilicate mineral that contains potassium, magnesium, iron and aluminium. ... Amphibole (Hornblende) The mineral hornblende is a complex silicate which is an isomorphous mixture of three molecules; a calcium-iron-magnesium silicate, an aluminium-iron-magnesium silicate, and an iron-magnesium silicate. ... The pyroxenes are a group of important rock-forming silicate minerals found in many igneous and metamorphic rocks. ... Olivine The mineral olivine is a magnesium iron silicate with the formula (Mg,Fe)2SiO4 in which the ratio of magnesium and iron varies between the two endmembers of the series: forsterite (Mg-rich) and fayalite (Fe-rich). ...
Latite asserts the affirmative defenses of greater hazard and infeasibility.
Latite's accusation that Prince's inspection was unreasonable stems from two facts: (1) Prince videotaped Latite's employees on the roof prior to conducting an opening conference with Latite, and (2) Prince interviewed the employees and Winger without advising them that the video camera was on and was recording their interviews.
Latite does not argue that conventional methods of fall protection were technologically infeasible, only that the attachment of any form of fall protection to the soft pine used in the roof construction in South Florida would fail to hold the weight of an employee in the event of a fall.
