Carbonate Critical Zone: An NSF-Sponsored Workshop


Our planned in-person workshop has been postponed because of the COVID-19 pandemic. We are instead hosting a series of virtual sessions as a way to initiate the original workshop program, as well as to develop the next four years of the RCN activities.

Pennsylvania Field Workshop

AUGUST 2-5, 2020

The first Field Workshop will be held at Temple University with a field trip to Central PA Karst & Shale Hills CZO

Registration information will be posted in January 2020

Participant support is available through application!

Carbonate Critical Zone Workshop Overarching Theme

Critical zones can be considered a continuum between carbonate-rich and silicate-rich lithologies. Distributions of these two mineral types will impact most, if not all, CZ processes and functions. This workshop is organized around various themes to evaluate how mineral content impacts CZ processes. Initial themes are listed below, which will fertilize discussion at the workshop, but additional themes are expected to arise among workshop participants. Workshop outcomes will include development of working groups to continue discussion following the workshop that should lead to white papers, peer-reviewed publications, and seed ideas for proposal development.


CZ Architecture: Congruent dissolution of carbonate minerals provides distinct solute generation and export patterns compared with incongruent dissolution of silicate minerals

Climate and Land Use Change: Change resulting from human use of CZ, rising average global temperature, and increased extreme weather events will affect processes differently depending on mineralogical compositions of CZs.

Ecology: Biological processes impact acid formation, dissolution reactions, and solute generation which create feedbacks that support biological function but feedbacks likely have distinct rates and magnitudes depending on lithology.

Hydrology: Flow paths and rates will depend on the extent of incongruent relative to congruent mineral dissolution and in carbonate-rich CZ will form preferential flow paths such as caves and conduits.

Time: CZ processes range from event to geological time scales and are likely to impact CZ processes given differing reaction rates of silicate and carbonate minerals.

Weathering: Delivery of acids to and types of acids found in CZs will determine weathering reaction mechanisms and rates, which will vary depending on the lithological characteristics of the CZ.
