Alteration, fractional crystallization, partial melting, mantle properties from trace elements in basalts recovered in the north atlantic
.-Alkali metals prove to be very sensitive to alteration process even if this process is moderate. It is very difficult to use these elements to trace magmatic processes since their concentration may Vary within an homogeneous "unaltered" unit. From all the basaltic units investigated, a c...
