Geological studies across multiple basins and epochs consistently document the presence of cross-stratified, parallel-stratified, and otherwise internally stratified conglomerates within fan delta sedimentary deposits.
The claim specifies that cross-stratified conglomerates form within fan delta sedimentary deposits. This is a specific, empirical geological statement that is easily verified through sedimentological literature. Multiple papers (e.g., [0], [2], [5], [11]) explicitly identify stratified or cross-stratified conglomerate facies within various fan delta formations worldwide. There are no refuting papers; therefore, the balance of evidence clearly supports the claim.
