隕石也稱“隕星”，是地球以外脫離原有運(yùn)行軌道的宇宙流星或塵碎塊飛快散落到地球或其它行星表面的未燃盡的石質(zhì)、鐵質(zhì)或是石鐵混合的物質(zhì)。
Meteorite, also known as "meteorite", is a kind of unburned stone, iron or stone iron mixed material that is rapidly scattered on the surface of the earth or other planets by cosmic meteor or dust fragments that are separated from the original orbit outside the earth.
大多數(shù)隕石來(lái)自于火星和木星間的小行星帶，小部分來(lái)自月球和火星。隕石大體可分為石質(zhì)隕石、鐵質(zhì)隕石，石鐵混合隕石。雖然隕石的形態(tài)各異，但這塊超級(jí)定向橄欖石隕石可稱的上“宇宙神石”，“上帝的禮物”。由于定向隕石在高速隕落的過(guò)程中，沒(méi)有經(jīng)過(guò)翻滾，長(zhǎng)時(shí)間按一定不變的方向成垂直狀態(tài)，直接隕落下來(lái)。這樣的隕石叫垂直定向隕落隕石。
Most meteorites come from the asteroid belt between Mars and Jupiter, and a small number from the moon and Mars. Meteorites can be roughly divided into stony meteorites, iron meteorites and mixed meteorites. Although the shapes of meteorites are different, this super oriented olivine meteorite can be called "cosmic God stone" and "God's gift". In the process of high-speed falling, the directional meteorite did not tumble and fell directly in a vertical state in a certain constant direction for a long time. Such a meteorite is called a vertical falling meteorite.
定向隕落的石隕石在墜落地面的過(guò)程中，在以每鈔15公里的速度進(jìn)入大氣層，產(chǎn)生了劇烈的摩擦，高強(qiáng)度的氣流和高溫形成了熱消溶，造成了對(duì)隕石頭部的溶蝕，形成了各種各樣的頭部氣線造形，也形成了石隕石本身的形態(tài)，大多數(shù)呈現(xiàn)大頭小尾、圓錐形的導(dǎo)彈形狀，這就是風(fēng)阻最低的空氣動(dòng)力流線造型，科研價(jià)值極高，研究意義重大。
During the process of falling to the ground, the directional meteorites enter the atmosphere at a speed of 15 km per note, resulting in severe friction. High intensity air flow and high temperature form heat dissolution, resulting in dissolution of the meteorite head, forming various head gas lines, and forming the shape of meteorites themselves. Most of them are large heads and small tails The shape of conical missile is the aerodynamic streamline with the lowest wind resistance. It has high scientific research value and is of great significance.
橄欖石，是地幔中含量非常豐富的一種礦物，寶石級(jí)的橄欖石多為橄欖綠色、黃綠色、濃綠色等。人類對(duì)橄欖石的使用可以追溯到公元前3500年，古埃及人在紅海邊的小島上開(kāi)采橄欖石作為寶石佩戴，被埃及人稱為“太陽(yáng)寶石”。
Olivine is a very rich mineral in the mantle. Gem grade olivine is mostly olive green, yellow green, dark green and so on. The use of olivine by human beings can be traced back to 3500 BC. Ancient Egyptians mined olivine on a small island by the Red Sea to wear it as a gem, which was called "Sun gem" by Egyptians.
橄欖石多呈粒狀，顆粒普遍偏小，玻璃光澤，內(nèi)部常有由包裹體和應(yīng)力裂隙組成的睡蓮葉狀包裹體;橄欖石具有較強(qiáng)的雙折射率，所以我們?cè)谟梅糯箸R觀察橄欖石的時(shí)候很容易看到橄欖石的內(nèi)部包裹體或者后刻面棱線出現(xiàn)雙影;除此之外，橄欖石獨(dú)特的橄欖綠色和鐵元素導(dǎo)致的吸收光譜也是它區(qū)別于其他寶石的鑒定特征。
Olivine is mostly granular, generally smaller and glassy, with water lily leaf like inclusions composed of inclusions and stress fissures; Olivine has a strong birefringence index, so we can easily see the double shadow of the internal inclusions or the back faceted edges of olivine when we observe olivine with a magnifying glass; In addition, olivine's unique olive green and absorption spectrum caused by iron are also its distinguishing features from other gemstones.
橄欖石的主要成分是鐵和鎂，同時(shí)含有錳、鎳、鈷等元素，是組成上地幔的主要礦物，也是月巖和隕石的主要礦物成分，此外橄欖石也在火星、部分彗星上出現(xiàn)過(guò)。當(dāng)這些天體碎片帶著橄欖石墜落到地球上便會(huì)形成橄欖石隕鐵，也被人們稱為“天寶石”，其中大顆粒的橄欖石晶體被鐵鎳合金包裹著，看起來(lái)和地球產(chǎn)出的寶石級(jí)橄欖石的品質(zhì)不相上下。
Olivine is mainly composed of iron and magnesium, and also contains manganese, nickel, cobalt and other elements. It is the main mineral composition of the upper mantle, as well as the main mineral composition of Moonstone and meteorite. In addition, olivine has also appeared on Mars and some comets. When these celestial body fragments fall to the earth with olivine, they will form olivine meteorite iron, also known as "celestial gem", in which large olivine crystals are wrapped by iron nickel alloy, which looks as good as the gem grade olivine produced by the earth.
隕石帶來(lái)的橄欖石中除了微量元素會(huì)和地球產(chǎn)出的橄欖石不同之外，這些天外來(lái)客中的包裹體形態(tài)也從未在地球產(chǎn)出的橄欖石中出現(xiàn)過(guò)。隕石中的橄欖石在顯微鏡下可以觀察到呈十字交叉狀的細(xì)針狀或絲狀包裹體，這種包裹體的形態(tài)目前在地球產(chǎn)出的橄欖石中還未發(fā)現(xiàn)，并且還未確定組成這種包裹體的物質(zhì)成分。
Except that the trace elements in olivine brought by meteorites are different from olivine produced by the earth, the inclusion morphology of these extraterrestrial visitors has never appeared in olivine produced by the earth. Olivine in the meteorite can be observed under the microscope in the form of crisscross fine needle like or filiform inclusions. The shape of this inclusion has not been found in the olivine produced by the earth, and the composition of this inclusion has not been determined.
此橄欖石隕石約重1006克，在隕石中的橄欖石帶著彗星慧核的溫度和慧發(fā)的瀟灑，帶著月巖的高冷，就這樣穿過(guò)宇宙來(lái)到地球上，給我們帶來(lái)的不只是一塊寶石，還有它作為彗星的一部分在宇宙中劃過(guò)的軌跡，還有我們從未見(jiàn)過(guò)的月球的背面。盡管它的稀有性限制了它的商業(yè)意義，但這并不妨礙一些專業(yè)礦物收藏者對(duì)它的喜愛(ài)。
This olivine meteorite weighs about 1006 grams. The olivine in the meteorite, with the temperature of comet's comet core, the natural and unrestrained of comet's comet hair, and the high cold of moon rock, came to the earth through the universe in this way, bringing us not only a gem, but also its track in the universe as a part of comet, as well as the back of the moon that we have never seen before. Although its rarity limits its commercial significance, it does not prevent some professional mineral collectors from loving it.
