An uncommon stone from a collector in Lanzhou drew enormous attention from many experts and collectors. The stone is imbedded with a screw-threaded metal bar and is suspected of being from outer space. Mr. Zhilin Wang found this stone on a field research trip to the Mazong Mountain area located on the border of Gansu and Xijiang provinces. The pear-shaped stone is extremely hard and has a mysterious black color. It is about 8 x 7 cm and weighs 466 grams.
The most surprising part of the stone is the embedded 6 cm cone-shaped metal bar which bears clear screw threads. This mysterious stone attracted attention from many geologists and collectors. The geologists and global physicists from many prestigious institutions gathered to study the origin of this mysterious stone.
After a discussion about its possibility of being man-made and the possible reasons for its formation, the scientists unanimously labeled the stone as one of the most valuable in China and in the world for collection, research, and archaeology studies. During the discussion, the scientists proposed many hypotheses about the formation of this stone, but found all incredible. The screw-threaded metal bar is tightly enclosed in the black lithical material. Neither the bar’s entrance to the stone nor the exposed bar tip appear to be man-made.
Moreover, the screw thread width remains consistent from the thick end to the thin end, instead of varying due to the growth of organisms. One of the hypotheses says that this stone could be a relic from a prehistoric civilization, equivalent to ours that may have existed on Earth before our recorded history.
Another one states that it could be a stony meteorite and could have brought the information of an extraterrestrial civilization. At the end of the conference, all scientists agreed that further research is needed to address questions such as how the stone was formed and whether the “metal bar” is truly metal, before the “visitor-from-outer-space” mystery can be solved.
