ABOUT THIS ISSUE
This issue of Elements celebrates the diverse contributions that the Earth sciences have made to characterizing, interpreting, conserving, and valorizing cultural heritage. As demonstrated in these articles, Earth scientists possess a profound perception of the complexity of natural materials, they have the necessary knowledge of the ancient and recent geological and physicochemical processes acting on natural materials and on the artifacts produced by human activities, and they employ techniques essential for the investigation of our common heritage. Earth scientists greatly contribute towards a better understanding and preservation of our past.

Volume 12, Number 2 (April) • The Enigmatic Relationship between Silicic Plutonic and Volcanic Rocks
The relationship between silicic volcanic and plutonic rocks has long puzzled geologists. Although the compositional evolution for volcanic and plutonic rock suites are virtually identical, there is much debate whether rhyolites form as melt extracted from granite plutons or whether the two rock types reflect wholly separate origins. This issue discusses the broad set of observations from petrology, geochronology, thermal modeling, geophysical techniques, and geochemistry that lead to contradictory interpretations and no simple description for the relationship. Discerning how silicic volcanic and plutonic rocks are connected will affect important Earth science questions such as “how is continental crust formed?” and “can we predict supereruptions?”
