| Description |
Dark grey-brown mass of druzy quartz on stalactites displaying capillary growth habit, in which hollowed out calcitic layers are formed by limestone in solution in water which dries and solidifies around the surface and builds hollow straws due to the adhesive and cohesive forces of water molecules, along with surface tension, which can form a meniscus later that defies gravity and grows upward, sideways, or in unique hollow cones as shown in this specimen. The capillary layers of limestone are then further coated by quartz, with some broken off, showing an incredible variety of natural processes all on this one, exemplary combination specimen. . |
