Ich bekam jetzt noch mal ein paar Namen für das grüne Küken genannt, z.B. Dushan Jade, danach gegoogelt und treffe auf eine interessante Seite zu fakenamen für Jade

da steht dann folgendes unter Dushan- Jade (lag ich gar nicht so falsch mit Epidot

:
Dushan Jade
"Dushan jade" is comprised of saussurite, not true jade.
"Dushan Jade" Example
In August 2006 I received email from someone demanding to know my source for this information, and called my page a "misleading bunch of bull". Setting the insults aside, the information on Dushan jade came fromR. V. Dietrich, Professor Emeritus from the College of Science and Technology, Central Michigan University. To quote:
Saussurite (also called Dushan jade, jade tenace, Nanyang jade, and Swiss jade) -This alteration product of some basaltic composition igneous rocks, or more particularly to their plagioclase feldspar component, consists largely of albite (sodium-rich plagioclase feldspar) and epidote and/or zoisite (both epidote group minerals) and commonly also includes lesser percentages of calcite and sericitic mica plus or minus one or more of the zeolite group minerals and/or prehnite. Some saussurite appears macroscopically homogeneous -- indeed it was once considered to be a mineral species. - [Distinguishing saussurite from jade by macroscopic means can be difficult -- e.g., both its typical hardness and specific gravity fall within the range of those of jade; thus, it is fortunate, and noteworthy, that saussurite is rarely found in pieces of desirable color that are large enough to be carved (etc.) so it has found little use as a jade substitute.].
Another website called "Chinese Jade Gifts" even states: "Nanyang jade: A kind of plagioclase rock with a hardness of 6-6.5 degree from Dushan, Nanyang, Henan province. So sometimes it is called Dushan jade." Sorry to say, but "plagioclase rock" is a feldspar, not jadeite or nephrite.
Mieneralienatlas sagt zu Saussurit:
"Begriff für die Alterung von basischem Plagioklas zu einem feinkörnigen Aggregat von Na-Plagioklas und Epidot, zusammen mit Calcit, Glimmer und ggf. farblosen Amphibolen, welche den Epidot ersetzen können. Die Ursache der Saussuritisierung ist ein geringer Metamorphismus basischer magmatischer Gesteine.
Die Mischung wurde ursprünglich als eigenes Mineral Saussurit angenommen."
