晚白垩世至早第三纪（79.5 ± 3.5 ~ 60.7 ± 2.4Ma）Osecna Com-1黄长石岩系的岩墙
Plex和Devil's Walls岩墙群，包括Scheumann（1913）的超镁铁质层状岩（polzenites），
分布在波希米亚北方的整个普卢奇尼采河上游流域。
橄榄岩及伴生黄长石岩具有橄榄石+黄长石±霞石的矿物组合特征。
钙钛矿、尖晶石、方解石、钙钛矿、尖晶石和磷灰石。关于其矿物和化学成分的新数据
从原来的舒曼的地方组成（Vesec，Modlibohov，Luhov类型）反对废除
根据Le Maitre（2002）的分类，超镁铁质层状岩属于超镁铁质层状岩，术语为“polzenite”和“alnoite”。
被称为Osecna杂岩的叶岩状体的边缘相和许多平坦隆起显示出橄榄石
微黄长石组成（层状相）。斑状结构、化学成分和
特征矿物如钙镁橄榄石和金云母表明它们与超镁铁质层状岩- polze-
Vesec类型的Nites。含黄长石的橄榄霞岩到橄榄黄长石（橄榄石+单斜辉石+霞石
+ 黄长石土和含磷灰石的尖晶石）形成了一群被称为魔鬼墙的平行岩墙。
Scheumann的非黄长石岩脉岩石“wesselite”，在空间上与玻长岩有关，经常被错误地归因于
属于钾镁矾组，是一种碱性钾镁矾，由钾镁矾+金云母组成
+ 含单斜辉石、金云母、方沸石、方沸石、钛镁云母的基质中的透辉石+橄榄石斑晶，
黑云母、磷灰石±玻璃/斜长石）。首次K-Ar数据显示渐新世年龄（30.9 ± 1.2 ~ 27.8 ± 1.1 Ma），
普通的凝灰岩-碧玄岩系列。
Dykes of the Late Cretaceous to Early Tertiary (79.5 ± 3.5 to 60.7 ± 2.4 Ma) melilitic rock series of the Osecna Com-
plex and the Devil’s Walls dyke swarm, including ultramafic lamprophyres – polzenites – of Scheumann (1913) occur
dispersed in the entire Upper Ploucnice River basin in northern Bohemia.
Polzenites and associated melilitic rocks are characterized by the mineral association of olivine + melilite ± nephe-
line, hauyne, monticellite, phlogopite, calcite, perovskite, spinels and apatite. New data on their mineral and chemical
compositions from original Scheumann’s localities (the Vesec, Modlibohov, Luhov types) argue against the abolition
of the group of ultramafic lamprophyres and the terms ‘polzenite’ and ‘alnoite’ by the Le Maitre (2002) classification.
Marginal facies and numerous flat apophyses of the lopolith-like body known as the Osecna Complex show an olivine
micro-melilitolite composition (lamprophyric facies). The porphyritic texture, chemical composition and the presence of
characteristic minerals such as monticellite and phlogopite point to their affinity with ultramafic lamprophyres – polze-
nites of the Vesec type. Melilite-bearing olivine nephelinites to olivine melilitites (olivine + clinopyroxene + nepheline
+ melilite ± hauyne and spinels with apatite) form a swarm of subparallel dykes known as the Devil’s Walls.
The Scheumann’s non-melilite dyke rock “wesselite”, spatially associated with polzenites and often erroneously attributed
to the polzenite group, is an alkaline lamprophyre of monchiquite to camptonite composition (kaersutite + phlogopite
+ diopside + olivine phenocrysts in groundmass containing clinopyroxene, phlogopite, hauyne, analcime, titanian mag-
netite, apatite ± glass/plagioclase). First K–Ar data show Oligocene ages (30.9 ± 1.2 to 27.8 ± 1.1 Ma) and an affinity to
the common tephrite–basanite rock series.
