23 Illitization of smectite in sedimentary systems, a process akin to ‘reverse 24 weathering’, is a diagenetic process that has significant implications for sediment 25 paragenesis and hydrocarbon exploration.

Altered volcanic tephra layers (i.e., 28 K-bentonites) characterized by an interstratified illite-smectite (I-S) clay mineralogy 29 serve as an excellent medium to investigate the illitization of smectite.
