Eclogite is a mafic metamorphic rock. Eclogite forms at pressures greater than those typical of the crust of the Earth. An unusually dense rock, eclogite can play an important role in driving convection within the solid Earth. The fresh rock can be striking in appearance, with red to pink garnet (almandine-pyrope) in a green matrix of sodium-rich pyroxene (omphacite). Accessory minerals include kyanite, rutile, quartz, lawsonite, coesite, amphibole, phengite, paragonite, zoisite, dolomite, corundum, and, rarely, diamond. Plagioclase is not stable in eclogite. Eclogite typically results from high-pressure metamorphism of mafic igneous rock (typically basalt or gabbro) as it plunges into the mantle in a subduction zone. Such eclogites are generally formed from precursor mineral assemblages typical of blueschist-facies or amphibolite-facies metamorphism. Eclogite can also form from magmas that crystallize and cool within the mantle or lower crust. Eclogite is a rare and importan

From Muscat drive towards Nizwa (Fanja, Bidbid, Samail road #15) and at Firq roundabout and turn left taking the Salalah road via Adam. Refill supplies like ice for cool boxes and fill gas at Shell in Adam. QARAT AL MILH Drive further on road #31 towards Haima and take the off-road turn at (21°45'21.8"N 57°19'57.7"E) to view Qarat Al Milh - a smaller Salt Mountain (21°45'50.5"N 57°17'30.1"E) for a photo-stop. Now join road#29 through off-road laid along at (21°45'56.7"N 57°17'15.1"E) and join the road #31 again towards Ghaba.    At (21°27'01.2"N 57°16'43.9"E) on road#31 turn right and join the connecting off-road by turning right again at (21°24'39.2"N 57°07'07.0"E) and take the right branch off-road at (21°28'19.8"N 57°07'34.2"E) to reach Qarat Al Kibrit (21°30'35.0"N 57°08'57.2"E) .   Geologically speaking, this is a massive of Pre-cambrain Halite.

A carbon sink is a natural or artificial reservoir that accumulates and stores some carbon-containing chemical compound for an indefinite period. The process by which carbon sinks remove carbon dioxide (CO2) from the atmosphere is known as carbon sequestration. These wadi pools become isolated pools when the supply dries up. These white or blue, alkaline rock pools have white deposits at the bottom. The rocks are mantle peridotite, which reacts with CO2 to form white carbonates. Peridotite is found in Oman and a lot of other places, but basalt is more common: Two-thirds of the rocks on Earth are basaltic, and the whole ocean floor is basalt. Reactivity with CO2 is faster in mantle peridotite, but if you want to inject large volumes of dissolved CO2 then you need pore space in the rocks. Basalt has a much higher porosity than peridotite.
