石隕石是最常見的一種隕石,也是墜落最多的一類隕石。石隕石主要或全部由硅酸鹽礦物、特別是鐵鎂硅酸鹽組成的隕石的總稱,同時含有少量的鎳鐵合金及硫鐵化物。根據巖石結構有無球粒存在,石隕石又分為球粒隕石和非球粒隕石兩大類。
中國是世界上最早記錄隕石的國家,《春秋》記:“(魯僖公)十有六年,春,王正月戊申朔,隕石于宋五。”而宋代沈括《夢溪筆談》載錄一零六四年的常州隕石:“治平元年,常州日禺時,天有大聲如雷,乃一大星,幾如月,見于東南。少時而又震一聲,移著西南。又一震而墜在宜興縣民許氏園中,遠近皆見,火光赫然照天,許氏藩籬皆為所焚。是時火息,視地中有一竅如棲大,極深,下視之,星在其中,熒熒然。良久漸暗,尚熱不可近。又久之,發其竅,深三尺余,乃得一圓石,猶熱,其大如拳,一頭微銳,色如鐵,重亦如之。”這段文字不僅記錄了隕石的墜落過程,還描述了其大小質地,為最早的明確可證為石隕石的文獻。
此石隕石呈不規則狀,表面晶體顆粒清晰可見,外表散布著不規則的氣印和熄滅冷卻后凝結的熔殼。且此隕石密度高,硬度高,個頭碩大,具有很強的可塑性,具有較高的市場價值和珍藏價值。
隕石收藏已經成為熱門一類,無論是個人的喜好,還是作為投資目標,眾多收藏大家紛紛加入隕石收藏行列,比如國外早有名氣的黑格,國內年輕收藏家李澤楷,都已經成為隕石收藏市場的高端收藏群體,隨著隕石市場的火爆,藏家選購隕石的標準也水漲船高,比如隕石的種類,品相還是重量,這些都制約了隕石在拍賣市場上的最終價格。此件隕石實為收藏投資之佳品。
Meteorites are the most common type of meteorites and the most falling type of meteorites. Stone meteorite is a general term for meteorites composed mainly or entirely of silicate minerals, especially iron-magnesium silicate. It also contains a small amount of nickel-iron alloys and ferroferrides. According to the presence or absence of chondrites in rock structures, stony meteorites are divided into chondrites and non-spherical meteorites.
China is the earliest country to record meteorites in the world. "Spring and Autumn" records: "(Lu Xiong) has ten years, spring, Wang Zhengyue, Wu Shenshuo, meteorites in Song Wu." The Changzhou meteorite in 1064: "In the first year of Zhiping, when Changyu was in Yuyu, the sky was loud like a thunder, but a big star, almost like the moon, seen in the southeast. Sometimes it shook again and again, moving to the southwest. It fell in the Xu Family Garden of the people of Yixing County. It was seen from far and near, the fire was shining brightly, and the Xu family barriers were all burned. It was time for the fire to breathe. Among them, yingyingran. It gradually dimmed for a long time, but it was still inaccessible. After a long time, it made its tricks, more than three feet deep, it was a cobblestone, still hot, its big as a fist, a sharp edge, like iron, heavy As such." This passage not only records the falling process of the meteorite, but also describes its size and texture. It is the earliest document that can be clearly identified as a meteorite.
This stone meteorite is irregular in shape, with a turquoise luster throughout, the crystal particles on the surface are clearly visible, and the outer surface is scattered with irregular gas marks and extinguished condensed molten crust. Moreover, the meteorite has high density, high hardness, huge size, strong plasticity, and high market value and precious value.
Meteorite collection has become a popular category. Whether it is a personal preference or an investment target, many collectors have joined the meteorite collection, such as the well-known foreign Hege, the domestic young collector Li Zekai, has become the meteorite collection market High-end collectors, with the popularity of the meteorite market, collectors' standards for buying meteorites have also increased. For example, the types of meteorites, the appearance or the weight, all restrict the final price of meteorites in the auction market. This meteorite is really a good product for collection and investment.
