Kye-Hun Park & Hubert Staudigel
Basalts from ODP Site 648, recovered from Serocki Volcano, a near-axis volcano on the Mid-Atlantic Ridge, are normal mid-ocean ridge basalts, depleted in K, Rb, and LREE. They have homogeneous source regions with 87Sr/88Sr = 0.70234 - 0.70245 (N = 6); 143Nd/,44Nd = 0.51318 - 0.51322 (N = 8); 208Pb/204Pb = 18.53 - 18.74; 207Pb/205Pb = 15.40 – 15.45; 208Pb/204Pb = 37.83 – 36.14 (n= 3). The recovered materials are generally fresh with minor initial...
