This replacement is compensated by a K-Pb substitution /Table 7.3-4«/. Because of the grinding-type sample preparation procedure - inevitably leading to strong thickness contrast features - the above details were impossible to observe in TEH. On the basis of the remarkably uniform appearance of the SAED images however, it can be supposed, that due to the above mentioned substitutions there is a continous transition between the pairs of alunitehinsdalite and alunite-osarizavaite

. At the same time, this can be taken for a proof for the isoaorphy of osarizavaite and hinsdalite with alunite - a possibility already suggested by other authors, too. There are also manganiferous incrustations in the Legyesbénye quarry. The material of these incrustations proved to consist of pyrolusite-, hollandite-, psilomelane-, etc. units, connected randomly on the unitcell level. Interestingly enough their X-ray diffraction pattern /Pig. 7./ shows a certain similarity to that of some deep-sea Un-nodules. As a result of recent soil forming processes lubunite /a modification of calcite, abnormally elongated in the direction of the {lull] rhombohedrons/ also appears in this locality. Its cottonlike lamellae cover the walls of the quarry in the form of soft aggregates.
