The book “Hypogene Karst Regions and Caves of the World” is going to be published by Springer, in its series “Cave and Karst Systems of the World”.
There will be a karst session at the AGU Fall 2016 Meeting in San Francisco, USA in December 12-16: Characterization, Modeling, and Remediation of Fissured, Carbonate, and Karst Groundwater Systems
A book "Höhlen und Karst in Österreich" (Caves and karst in Austria; Editors: Christoph Spötl, Lukas Plan & Ehrad Christian) will be printed until mid of July. Subscription is available.
Many inspiring ideas on caves can be found in images created by children, generated by the International Contest of Kid’s Drawing "Caves in the Eyes of our Children".

That keyhole passage; keyhole is 1. this very descriptive name derives from the crosssectional shape of a cave passage that consists of a phreatic tube with a vadose canyon cut in its floor. it is the classic example of a two-phase cave passage that originated and began its development in the phreas and was then modified by vadose entrenchment. as this sequence is the result of water table lowering by normal surface erosion, keyholes are common. some keyholes are so small that the lower slot is impassable and the caver has to squeeze along the upper tube; others are very large. spectacularly long is the 5km of keyhole forming the fissures in castleguard cave, canada. a tube 6m in diameter tops an irregular tapering canyon 15m deep that must be traversed on sloping ledges at mid-level . 2. a small passage or opening in a cave; in cross section, rounded at the top, constricted in the middle, and rectangular or flared out below . they appear as keyholes when viewed in cross section. they are formed when underground streams flowing in a tubular passage begin downcutting to form a canyon passage . see also canyon passage; passage; tubular passage; vertical shaft.?

The aim of this study is to characterize in detail, the mineralogy of different-shaped concretions as well as to investigate the physico-chemical parameters of the associated mine drainage and drip waters in the Santa Barbara level of the Libiola Mine (NW Italy) by several geochemical and mineralogical techniques. Under the term “minothems” we are grouping all those secondary minerals that occur under certain form or shape related to the conditions under which they formed but occur in a mine, or in any artificial underground environment (i.e., "mine speleothems"). Different types of minothems (soda straw stalactites, stalactites, and draperies) were sampled and analyzed. Mineralogical results showed that all the samples of stalactites, stalagmite and draperies are characterized by poorly crystalline goethite. There are significant differences either in their texture and chemistry. Stalactites are enriched in Zn, Cd, and Co in respect to other minothems and show botryoidal textures; some of these exhibit a concentric layering marked by the alternation of botryoidal and fibrous-radiating textures; the draperies are enriched in V and show aggregates of sub-spheroidal goethite forming compact mosaic textures. Geochemical investigations show that the composition and physico-chemical parameters of mine drainage and drip waters are different from the other acidic mine water occurrences in different areas of the Libiola Mine, where minothems are less abundant. All mine water samples contain Cu, Ni, and Zn in appreciable levels, and the physico-chemical conditions are consistent with the stability of ferrihydrite, which however tends to transform into goethite upon ageing.
