Petrographic and geochemical study on cave pearls from Kanaan Cave (Lebanon), 2007, Nader Fadi. H.
The Kanaan cave is situated at the coastal zone, north of Beirut City (capital of Lebanon). The cave is located within the upper part of the Jurassic Kesrouane Formation (Liassic to Oxfordian) which consists mainly of micritic limestone. Twenty seven cave pearls were subjected to petrographic (conventional and scanning electron microscopy) and geochemical analyses (major/trace elements and stable isotopes). The cave pearls were found in an agitated splash-pool with low mud content. They are believed to have formed through chemical precipitation of calcite in water over-saturated with calcium. The nucleus and micritic laminae show ? 18OV-PDB values of about -5.0 and ? 13C V-PDB values of -11.8, while the surrounding calcite spar laminae resulted in ?18OV-PDB ranging between -5.3 and -5.2, and ? 13C V-PDB between -12.3 and -12.1. A genesis/diagenesis model for these speleothems is proposed involving recrystallization which has selectively affected the inner layers of the cave pearls. This is chiefly invoked by sparry calcite crystals invading the inner micrite cortical laminae and the nuclei (cross-cutting the pre-existing mud-envelopes), and the slight depletion in ? 18O values from inner to outer cortical layers. The calculated ? 18OV-SMOW of the water (-4.2) matches with data on meteoric water signature for the central eastern Mediterranean region.

Reconstitution spéléogénique de la grotte de Kanaan (Antélias, Liban): contribution à la morphogenèse du nahr AnteliasReconstitution spéléogénique de la grotte de Kanaan (Antélias, Liban): contribution , 2009, Nehme C. , Jabbourgedeon B. , Gerard P. C. , Sadier B. , Delannoy J. J.


The use of passive seismological imaging in speleogenetic studies: an example from Kanaan Cave, Lebanon., 2013, Nehm C. , Voisin C. , Mariscal A. , Grard P. C. , Cornou C. , Jabbourgdon B. , Amhaz S. , Salloum N. , Badarosaliba N. , Adjiziangerard J. And Delannoy J. J.

Among many parameters that control the evolution of caves stands the volume of unconsolidated clay sediments generally produced by the alteration of the calcareous rocks. Here we introduce the use of a passive seismological imaging technique to investigate the clay deposits and estimate its total volume in a cave. Applied for the first time for speleogenesis studies, the HVSR (Horizontal / Vertical Spectral Ration) is a geophysical technique that can help better interpret cave geomorphology. We apply seismological spectral techniques (H/V ratio) on ambient noise vibrations to derive the clay volume, as well as its shape. This technique applied on the clay volume reveals some internal details, such as fallen blocks prior to the deposit accumulation and helps to understand deposit evacuation dynamics. The study focuses on the Kanaan Cave, located in Metn District, Lebanon, and reveals new stages related to the cave speleogenesis. This technique could be applied on ‘paragenetic’ caves where clay volume is frequently present in order to constrain the clay volume and reconstruct the buried floor shape of the cave, underneath the clay deposit.
