Yuan Q, Li M, Desch S, Ko B, Deng H, Garnero E, et al.
Nature . 2023 Nov; 623(7985):95-99. PMID: 37914947
Seismic images of Earth's interior have revealed two continent-sized anomalies with low seismic velocities, known as the large low-velocity provinces (LLVPs), in the lowermost mantle. The LLVPs are often interpreted...

Hansen S, Garnero E, Li M, Shim S, Rost S
Sci Adv . 2023 Apr; 9(14):eadd4838. PMID: 37018398
Ultralow velocity zones (ULVZs) are the most anomalous structures within the Earth's interior; however, given the wide range of associated characteristics (thickness and composition) reported by previous studies, the origins...

Li M, McNamara A, Garnero E, Yu S
Nat Commun . 2017 Aug; 8(1):177. PMID: 28769033
The Earth's lowermost mantle large low velocity provinces are accompanied by small-scale ultralow velocity zones in localized regions on the core-mantle boundary. Large low velocity provinces are hypothesized to be...

Williams C, Li M, McNamara A, Garnero E, van Soest M
Nat Commun . 2015 Nov; 6:8937. PMID: 26596781
Chemical differences between mid-ocean ridge basalts (MORBs) and ocean island basalts (OIBs) provide critical evidence that the Earth's mantle is compositionally heterogeneous. MORBs generally exhibit a relatively low and narrow...

Pommier A, Leinenweber K, Kohlstedt D, Qi C, Garnero E, Mackwell S, et al.
Nature . 2015 Jun; 522(7555):202-6. PMID: 26062512
The relative motion of lithospheric plates and underlying mantle produces localized deformation near the lithosphere-asthenosphere boundary. The transition from rheologically stronger lithosphere to weaker asthenosphere may result from a small...

Weber R, Lin P, Garnero E, Williams Q, Lognonne P
Science . 2011 Jan; 331(6015):309-12. PMID: 21212323
Despite recent insight regarding the history and current state of the Moon from satellite sensing and analyses of limited Apollo-era seismic data, deficiencies remain in our understanding of the deep...

Marquardt H, Speziale S, Reichmann H, Frost D, Schilling F, Garnero E
Science . 2009 Apr; 324(5924):224-6. PMID: 19359580
Seismic shear anisotropy in the lowermost mantle most likely results from elastic shear anisotropy and lattice preferred orientation of its constituent minerals, including perovskite, post-perovskite, and ferropericlase. Measurements of the...

Hutko A, Lay T, Revenaugh J, Garnero E
Science . 2008 May; 320(5879):1070-4. PMID: 18497297
Earth's lowermost mantle has thermal, chemical, and mineralogical complexities that require precise seismological characterization. Stacking, migration, and modeling of over 10,000 P and S waves that traverse the deep mantle...

Garnero E, McNamara A
Science . 2008 May; 320(5876):626-8. PMID: 18451293
Processes within the lowest several hundred kilometers of Earth's rocky mantle play a critical role in the evolution of the planet. Understanding Earth's lower mantle requires putting recent seismic and...

Schmerr N, Garnero E
Science . 2007 Oct; 318(5850):623-6. PMID: 17962558
Using high-resolution stacks of precursors to the seismic phase SS, we investigated seismic discontinuities associated with mineralogical phase changes approximately 410 and 660 kilometers (km) deep within Earth beneath South...
