The history of vents during the 1961-2012 eruption of Pacaya volcano in Guatemala (Matias et al., 2012) clearly shows that the present surface of a composite cone reveals only a fraction of the total vent population.
There are 8 categories but three, composite cone, dome and caldera, each have an extra listing to denote the vents that have had historic activity.
Berlin, Germany, March 19, 2015 --(PR.com)-- During the IDS—the International Dentalshow in Cologne—berlin-based company botiss biomaterials GmbH has launched three innovative products: maxgraft[R] cortico[R], a new version of the well-known mucoderm[R] matrix and collacone[R] max, an improved biomimetic composite cone. These were designed for particular dental indications such as shell, socket seal and socket preservation techniques.
collacone[R] max is an innovative, biomimetic composite cone designed for socket preservation, which supports the osseous regeneration of the alveolus and prevents soft tissue collapse.

The SoundPoles each contain seven 2" x 3" EOSS designed, Kevlar composite cone
drivers and one ribbon tweeter mounted in a column enclosure, 1/16" thick.
Nineteen speakers (tweeters and midrange speakers with titanium cones; woofers with polypropylene composite cones
"It's the roots of three volcanoes that are composite cones
formed in the Mid-Continent rift system with deep fault structures that went deep into the mantle, tapped these balsaltic magmas and intrusions that have platinum, palladium and copper in them, which came up along the fractures."
