Guest guest Posted November 27, 2002 Report Share Posted November 27, 2002 Lebanon isn't really known for its minerals. There are some EXCELLENT fossils there, shale, sandstone and chert are common, as well as many varieties of limestone and conglomerate stone. Sometimes the limestone will contain veins of quartz, but this is nothing unusual as quartz is so common. Sometimes you'll find coral or other fossils that have been silicified. The organic parts of the creature are replaced by silica, thus creating quartz and opal. So its not inconceivable that you could find small amounts of these materials in the form of a fossil or cast. Occasionally small amounts of amber are found, but its not gemmy material due to being very brittle. Supposedly this amber sometimes contains good insect matter though. Due to its past volcanic activity, finds of basalt and lava rock are common. Coal can also be found. There are caves where one can find dolomitic limestone, which sometimes forms as crystals. Sometimes in these caves one can find geodes containing quartz crystals. Dolomite is always found below the earth's surface. Dolomite beds begin as calcite and aragonite-rich limestone, but magnesium-rich groundwater with a high saline level that you'll find near oceanic areas flows across the bed and changes it into dolomite. Hence the forementioned calcite- you'll sometimes find calcite that hasn't been metamorphosed into dolomite. Most of Lebanon in the past was an area of ocean, so thats why there are so many fossils and the dolomite that is formed by salty water. This was all I could learn in my geology links about Lebanon- sorry I couldn't help you more. Happy hunting! Blessings, Samantha Quote Link to comment Share on other sites More sharing options...
Guest guest Posted November 28, 2002 Report Share Posted November 28, 2002 1.4 MINERALS OF LEBANON There are few 'exciting' minerals in Lebanon. Good crystals of calcite are common and sometimes calcite or quartz filled geodes occur in rocks. Metallic minerals appear to be confined to the iron ores of haematite and limonite.
