The results indicated that the extraction rate of mineral from pollen in 70℃ water was the highest. the extraction rates of four mineral: Fe, Zn, Cu and Mn were 6. 931％, 52. 786％, 44. 443％ and 46. 549％ respectively. Second speciation presented in the form of exchangeable and nonexchangeable speciations, organic and inorganic speciations at the same time. The contents of both Fe and Mn in nonexchangeable speciation were more than 50％, most contents of Fe、 Zn、Cu、Mn were inorganic speciation. Among the four elements, the content of protein binding speciation of Fe was the highest: 47. 305％. The average mineral contents of soluble carbohydrate and grease binding speciation were less than protein binding speciation.

Peridotite xenoliths from Nüshan, Hannuoba and the Subei basin of the North China block have much lower water contents than those from other localities of the world (South Africa craton, New Mexico, Colorado plateau and basin and Range province of USA, South Mexico, French Central Massif and West Kettle of Canada). This difference is probably induced by the thermal erosion of asthenosphere during Mesozoic-Cenozoic period in the North China block.
