His earliest research was on problems of adsorption of gases on chabazite and other zeolites. It is closely related to the very similar mineral chabazite. These include analcime, thomsonite, mesolite, chabazite, and others. Many different materials that are isostructural with the chabazite mineral have been synthesized in laboratories. It is known for producing calcite, chabazite, nontronite, phillipsite, and thomsonite. Zeolite minerals such as chabazite and stilbite can also be found at Partridge Island. Associated minerals include other zeolites, especially chabazite, quartz, aragonite and calcite. The mineral "seebachite" (synonym of chabazite) is named in his honor. Chabazite occurs most commonly in voids and amygdules in basaltic rocks.
