摘要

在Chansin采石场(比利时)，发现了一个似乎完全被填满的水平岩溶画廊。对该充填物的研究表明，它是由基岩中残留的蚀变岩组成的。鬼岩岩溶作用在岩溶形成的第一阶段结束后就停止了。残留的蚀变岩仍然存在，没有明显的几何变化。未改变的基岩和鬼岩之间的过渡非常明显。我们提出了这个鬼岩的特征，这里把它看作一个典型的伪画廊，并作为进一步定义的参考。

The ghost-rock of the Chansin quarry (Belgium) – A remarkable example of pseudogallery

In the Chansin quarry (Belgium), a horizontal karstic gallery which seems to be totally filled has been discovered. The study of this filling shows that it is composed of a residual alterite from the bedrock. The ghost-rock karstification has stopped just after the first phase of this karstogenesis. The residual alterite is still present, without significant geometrical modification. The transition between the unaltered bedrock and the ghost-rock is very clear. We present the characteristics of this ghost-rock which is here regarded as a typical example of a pseudo-gallery and act as a reference for further definition.

期刊介绍： Geologica Belgica is a Belgian journal that welcomes papers concerning all aspects of the earth sciences, with a particular emphasis on the regional geology of Belgium, North West Europe and central Africa. Papers not dedicated to the geology of Belgium, North West Europe and central Africa are only accepted when one of the authors is linked to a Belgian University or Institution. Thematic issues are highly appreciated. In this case, guest editors take in charge the selection of the manuscripts and the subject of the papers can be enlarged. The journal is in open access. Submitted manuscripts should be concise, presenting material not previously published. The journal also encourages the publication of papers from Belgian junior authors. Short letters are accepted. Papers written in English are preferred. Each mansucript will be reviewed by at least two reviewers.
