Through the palagonitic alteration the fragmental character is somewhat obscured, zeolites being extensively developed in the interstices.
But I must repeat, that zeolites is very rare in this cave, and having myself broken off all the specimens that I was able to see, I doubt whether those who may visit the place after me will find any quantity of it.
The ones that looked like zeoliteswere zeolites, all right, or something very much like it.
It is possible that some of the other zeolites as mentioned under Bergen Hill occur here, but I have not been able to find them.
This is also partly true of the zeolites and granular limestone species with included minerals.
They may also become cellular--form zeolites in their cavities with foliated carbonate of lime, as well as minerals which commonly occur in amygdaloid.
Sometimes the metamorphism extends many feet from the point of contact; nay, more than that, somezeolites and other minerals seem to be developed in the crystallised limestone.
Chabazite occurs with other zeolites in the amygdaloidal cavities of basaltic rocks; occasionally it has been found in gneisses and schists.
Gmelinite and levynite are other species of zeolites which may be mentioned here, since they are closely related to chabazite, and like it are rhombohedral and frequently twinned.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "zeolites" in a variety of sentences. We hope that you will now be able to make sentences using this word.
