| Research Abstract |
Quantitative evaluation methods of dissolution for marine carbonates(foraminifera) using Micro-focus X-ray Computing Tomography(MXCT) has developed. Quantity of carbonate dissolution is expressed by total CT value as shell volume, and mean CT value as shell density. Availability and usefulness of this method was confirmed for natural and laboratory samples.
