摘　　要：Since the discovery of cosmic dust from Suzhou A-type granite, a following new problem is whether cosmic dust is preserved in only one type granite or in different types. In order to make the problem clear, the authors carried out many field and room investigations on I-type granite of western Suzhou, and found out that Suzhou I-type granite also could retain microspherules. Studies about these microspherules indicate that they are of ablated cosmic dust.

关 键 词：COSMIC DUST MICROSPHERULE GRANITE Suzhou.
