摘要:
紫绿玛瑙为全世界稀缺品种,近年来发现的洛南紫绿玛瑙为21世纪中国宝玉石资源重大发现,其古称紫玉,近代称为洛翠玉,2012年宝玉石界命名为紫绿玛瑙,因其产于华山南麓,亦称华阳玉,为中国目前紫绿玛瑙唯一产地。其质地温润坚毅,色彩饱和浓艳,色调丰富,色差截然,层次分明,组合多样,可雕性好,资源稀缺受到市场追捧,业界学者将紫绿玛瑙列为市场新贵,与翡翠、和田玉、南红玛瑙并称四大国玉,有“九色之首,百玉之尊”雅称。研究认为其产出层位为长城系杜关组上段下部原划紫红色、灰绿色泥岩,厚约5~17米,实际为一套同生沉积火山碎屑岩、沉凝灰岩。玛瑙产出层位受该层火山岩控制;矿带展布受白花岭–路家街复向斜之路家街复向斜南北两翼控制;其宝玉石资源分类为石英岩玉及蚀变白云岩玉大类。文章提出紫绿玛瑙定义,对赋矿地层杜关组进行厘定,探讨了地质特征、成因、资源分类,结合市场走势,对其品级进行分类。提出综合开发构想,认为只有采用不同流派的雕工艺术,将紫绿玛瑙稀缺性赋予深厚的洛南文化、中华文化元素,才能实现价值最大化;只有综合开发利用,多元化产业发展,才能实现美丽农村建设,以稀缺资源助推地方经济腾飞。对紫绿玛瑙相关资源规划、勘查,产业布局,商业开发、原料采购、文玩收藏、鉴赏等均有借鉴意义。

The purple and green agate is a rare species in the world. In recent years, the discovery of the purple and green agate of Luonan is a major discovery of treasure jade stone in China in the 21st century. Its ancient name is purple jade. In modern times it is called Luocui jade, and in 2012 treasure jade stone world named it as the purple and green agate. Because it is produced in the south foot of Huashan, it is also known as Huayang agate. Its material properties can be described as warm and firm; the color saturation is gaudy, rich in tone, chromatic aberration is distinct, the combination is diversiform, and it can be easily carved. Because of its scarce resource, the scholars of the industry listed the purple and green agate as the new aristocracy of the market; it is known as one of the four major jades of China along with jade, Hetian jade and southern red agate, and it is called “The head of the nine colors, the honor of all the jades”. According to the research, the output layer is the original purplish red and lime-green mudstone on the bottom of the upper part of the Duguan group in the Great Wall series, which is about 5 - 17 meters thick, and it is actually a set of syngenetic sedimentary pyroclastic and sedimentary limestone. The level of agate output layer is controlled by the volcanic rock. The mine strip is controlled by the north and south wing of the road homing street in the street of the white flower-road. Its treasure jade stone resources are classified as quartzite jade and the alteration of dolomite. The article puts forward the definition of agate, and discusses the geological characteristics, causes, resource classification and the classification of the grade in the mineralization stratum. The concept of comprehensive development is put forward, and it is thought that only by adopting the art of carving of different schools and making the purple and green agate scarcity to the deep Luonan culture and Chinese cultural elements can the value maximization be realized. Only by comprehensive development and utilization, and diversified industrial development can the construction of beautiful countryside be realized, and can the local economy be boosted by scarce resources. It can be used for reference for the planning, exploration, industrial layout, commercial development, raw material purchasing, art collection and appreciation.
